9 Application of Computer in Research

P.G. Padma Gowri

Introduction :

The computers are the emerging tool in the research process. The main components of Computers are an input device, a Central Processing Unit and an output device. It is an essential tool for research, whether for academic purpose or for commercial purpose. Computers play a major role today in every field of scientific research from genetic engineering to astrophysics research.

Computers with internet led the way to a globalized information portal that is the World Wide Web. Using WWW, researcher can conduct research on massive scale. Various programs and applications have eased our way into computing our research process. In this module, various computer software applications and tools are discussed with respect to research activities like data collection, analysis, etc.

Objectives:

• Understand the Features of computers.
• To know various steps involved in research process.
• Role of Computers in Research Publication.
• Introduction of Analysis Tools used in research process.

Features of a computer :-

There are many reasons why computers are so important in scientific research and here are some of the reasons are:

SPEED: computer can process numbers and information in a very short time. So researcher can process and analyze data quickly. By saving time researcher can conduct further research. A calculation that may take a person several hours to process will take computer mere minutes, if not seconds.

STORAGE DEVICE – Computer can store and retrieve huge data. It can be used when needed.

There is no risk of forgetting and loosing data.

ACCURACY: Computer is incredibly accurate. Accuracy is very much important in scientific research. Wrong calculation could result an entire research or project being filled with incorrect information.

ORGANIZATION: We can store millions of pages of information by using simple folders, word processors & computer programs. Computer is more productive & safer than using a paper filing system in which anything can be easily misplaced.

CONSISTENCY: computer cannot make mistakes through “tiredness” or lack of concentration like human being. This characteristic makes it exceptionally important in scientific research. Large calculations can be done with accuracy and speed with the help of computer.

Automatic Device – The programs which are run on computer are automatic through some  instructions

Computational Tools

Computers started for the use of powerful calculators, and that service is important to research today. Huge amount of data can process with the help of computer’s. Statistical programs, modelling programs and spatial mapping tools are all possible use of computers. Researchers can use information in new ways, example layering different types of maps on one another to discover new patterns in how people use their environment.

C ommunication

Building knowledge through research requires communication between experts to identify new areas requiring research and debating results and ideas. Before the invention of computers, this was accomplished through papers and workshops. Now, the world’s experts can communicate via web chatsor email. Information can be spread various ways example by virtual conferences

Researchers can take computers anywhere, it is easier to conduct field research and collect large amount of data. New areas of research in remote areas or at a community level are carried out by the mobility of computers. Social media sites have a new medium for interaction with society and collect the information.

The Steps in Research Process

Research process consists of series of actions necessary to carry out research work effectively  The sequencing of these steps listed below

• Formulating the research problem;
• Extensive literature survey;
• Developing the hypothesis;
• Preparing the research design;
• Determining sample design;
• Data Collection;
• Project Execution;
• Data Analysis;
• Hypothesis testing;
• Generalizations and interpretation,
• Preparation of the report or presentation of the results, i.e., formal write-up of conclusions of the research.

Computers in Research

Computers are used in scientific research extremely and it is an important tool .Research process can also be done through computers. Computers are very useful and important tool for processing huge number of samples. It has many storage devices like compact discs and auxiliary memories. Data can be used from these storage devices and retrieved later on. There are various steps necessary to effectively carry out research and the desired sequencing of these steps in the research process. This data can be used for different phases of research process.

There are five major phases of the research process:

• Conceptual phase
• Design and planning phase
• Data collection phase
• Data Analysis phase and
• Research Publication phase

Conceptual Phase and Computer

The conceptual phase consists of formulation of research problem, extensive literature survey, theoretical frame work and developing the hypothesis.

Computer helps in searching the existing literature in the relevant field of research. It helps in finding the relevant existing research papers so that researcher can find out the gap from the existing literature. Computers help for searching the literatures and bibliographic reference stored in the electronic database of the World Wide Web’s.

It can be used for storing relevant published articles to the retrieved whenever needed. This has the advantage over searching the literatures in the form of journals, books and other newsletters at the libraries which consume considerable amount of time and effort.

Bibliographic references can also be stored in World Wide Web. In the latest computers, references can be written easily in different styles. Researcher need not visit libraries .It helps to increase time for research. It helps researchers to know how theoretical framework can be built.

Design and Planning Phase and Computer

Computer can be used for, deciding population sample, questionnaire designing and data collection. They are different internet sites which help to design questionnaire. Software’s can be used to calculate the sample size. It makes pilot study of the research possible. In pilot study, sample size calculation, standard deviations are required. Computer helps in doing all these activities.

Role of Computers in Data collection phase

Empirical phase consists of collecting and preparing the data for analysis:

In research studies, the preparation and computation of data are the most labor-intensive and time consuming aspect of the work. Typically the data will be initially recorded on a questionnaire or record for suitable for its acceptance by the computer. To do this the researcher in connection with the statistician and the programmer, will convert the data into Microsoft word file or excel spreadsheet or any statistical software data file. These data can be directly used with statistical  Software’s for analysis.

Data collection and Storage:

The data obtained from the research subjects are stored in computes in the form of word files or excel spread sheets or any statistical software data file. This has the advantage of making  necessary corrections or editing the whole layout of the tables if needed, which is impossible or time consuming incase of writing in hand written. Thus, computers help in data editing, data entry, and data management including follow up actions etc. computers also allow for greater flexibility in recording and processing the data while they are collected as well as greater ease during the analysis of these data.

Data exposition:

The researchers are anxious about seeing the data: what they look like; how they are distributed etc. Researchers also examine different dimension of variables or plot them in various charts using a statistical application.

Data Analysis and Computer:

Data Analysis and Computer phase consist of the analysis of data, interpretation and hypothesis testing. Data analysis phase consist of statistical analysis of the data and interpretation of results. Data analysis and interpretation can be done with the help of computers. For data analysis, software’s available. These software help in using the techniques for analysis like average, percentage, correlation and all the mathematical calculations.

Software’s used for data analysis are SPSS, STATA, SYSAT etc. Computers are useful not only for statistical analysis, but also to monitor the accuracy and completeness of the data as they are collected. This software’s also display the results in graphical chart or graph form.

Computers are used in interpretation also. They can check the accuracy and authenticity of data. It helps is drafting tables by which a researcher can interpret the results easily. These tables give a clear proof of the interpretation made by researcher.

Role of Computer in Research Publication

After interpretation, computer helps is converting the results into a research article or report which can be published. This phase consists of preparation of the report or presentation of the results, i.e., formal write-up of conclusions reached. This is the research publication phase. The research article, research paper, research thesis or research dissertation is typed in word  processing software and converted to portable data format (PDF) and stored and/or published in the world wide web. Online sites are available through we can convert our word file into any format like html, pdf etc.

Various online applications are also available for this purpose. Even one can prepare our document using online word processing software and can store/edit/access it from anywhere using internet.

References and computer:

After completing the word document, a researcher need to give source of the literature studied and discussed in references. Computers also help in preparing references. References can be written in different styles. All the details of author’s journals, publication volume Books can be filled in the options “reference‟ given in computer and it automatically change the information into the required style. Software used to manage the references.

A researcher needs not to worry about remembering all the articles from where literature in taken, it can be easily managed with the help of computers.

Simulation:

Simulation is the imitation of the operation of a real-world process or system over time. Simulation is used in many contexts, such as simulation of technology for performance optimization, safety engineering, testing, training, education, and video games. Often, computer experiments are used to study simulation models. Simulation can be used to show the eventual real effects of alternative conditions and courses of action. Simulation is mainly used when the real system cannot be engaged, because it may not be accessible, or it may be dangerous or unacceptable to engage, or it is being designed but not yet built, or it may simply not exist. Using computers the simulation in research carried out in various fields.

Role of Computers in Scientific Research:

There are various computer applications used in scientific research. Some of the most important applications used in scientific research are data storage, data analysis, scientific simulations, instrumentation control and knowledge sharing.

Data Storage

Experimentation is the basis of scientific research. Scientific experiment in any of the natural sciences generates a lot of data that needs to be stored and analyzed to derive important conclusions, to validate or disprove hypotheses. Computers attached with experiential apparatuses, directly record data as its generated and subject it to analysis through specially designed software. Data storage is possible in SPSS data file, lotus spreadsheet, excel spreadsheet, DOS text file etc

Data Analysis

Analyzing Huge number of statistical data is made possible using specially designed algorithms that are implemented by computers. This makes the extremely time-consuming job of data analysis to be matter of a few minutes. In genetic engineering, computers have made the sequencing of the entire human genome possible. Data got from different sources can be stored and accessed via computer networks set up in research labs, which makes collaboration simpler.

Scientific Simulations

One of the prime uses of computers in pure science and engineering projects is the running of simulations. A simulation is a mathematical modeling of a problem and a virtual study of its possible solutions.

For example, astrophysicists carry out structure formation simulations, which are aimed at studying how large-scale structures like galaxies are formed. Space missions to the Moon, satellite launches and interplanetary missions are first simulated on computers to determine the best path that can be taken by the launch vehicle and spacecraft to reach its destination safely.

Instrumentation Control

Most advanced scientific instruments come with their own on-board computer, which can be programmed to execute various functions. For example, the Hubble Space Craft has its own onboard computer system which is remotely programmed to probe the deep space. Instrumentation control is one of the most important applications of computers.

Knowledge Sharing through Internet

In the form of Internet, computers have provided an entirely new way to share knowledge. Today, anyone can access the latest research papers that are made available for free on websites. Sharing of knowledge and collaboration through the Internet has made international cooperation on scientific projects possible.

Through various kinds of analytical software programs, computers are contributing to scientific Research in every discipline, ranging from biology to astrophysics, discovering new patterns and providing novel insights.

When the work in neural network based artificial intelligence advances and computers are granted with the ability to learn and think for them, future advances in technology and research will be even more rapid.

Tools and Applications Used In the Research Process Statistical Analysis Tool: SPSS

SPSS is the most popular tool for statisticians. SPSS stands for Statistical Package for Social Sciences.

It provides all analysis facilities like following and many more.

• Provides Data view & variable view
• Measures of central tendency & dispersion
• Statistical inference
• Correlation & Regression analysis
• Analysis of variance
• Non parametric test
• Hypothesis tests: T-test, chi-square, z-test, ANOVA, Bipartite variable….
• Multivariate data analysis
• Frequency distribution
• Data exposition by using various graphs like line, scatter, bar, ogive, histogram,

Data Analysis Tool:

Spreadsheet Packages

A spreadsheet is a computer application that simulates a paper worksheet. It displays multiple cells that together make up a grid consisting of rows and columns, each cell containing eitheral phanumeric text or numeric values. Microsoft Excel is popular spreadsheet software. Others spreadsheet packages are Lotus 1-2-3Quattro Pro, Javeline Plus, Multiplan, VisiCalc, Supercalc, Plan Perfect etc.

Other Statistical Tool

SAS, S-Plus, LISREL, Eviews etc.

Word Processor Packages

A word processor (more formally known as document preparation system) is a computer application used for the production (including composition, editing, formatting, and possibly printing) of any sort of printable material.

The word processing packages are Microsoft Word, WordStar, Word perfect ,Amipro etc.

Presentation Software

A presentation program is a computer software package used to display information, normally in the form of a slide show. It typically includes three major functions: an editor that allows text inserted and formatted a method for inserting and manipulating graphic images and a slideshow system to display the content. The presentation packages are Microsoft Power point, Lotus Freelance Graphics, Corel Presentations, Apple keynote etc.

DATABASE MANAGEMENT PACKAGES (DBMS)

Database is an organized collection of information. A DBMS is a software designed to manage adatabase. Various Desktop Databases are Microsoft Access, Paradox, Dbase or DbaseIII+, FoxBase, Foxpro/ Visual Foxpro, FileMaker Procommercial Database Servers that supports multiuser are Oracle, Ms-SQL Server, Sybase, Ingres, Informix, DB2 UDB (IBM), Unify, Integral, etc.

Open source Database packages are MySQL, PostgreSQL, and Firebird etc. BROWSERS  A web browser is a software application which enables a user to display and interact with text, images, videos, music, games and other information typically located on a Web page at a website on the World Wide Web or a local area network.

Examples are Microsoft Internet explorer, Mozilla firefox, Opera, Netscape navigator, Chrome.

Computer has helped in serving the difficulties faced by human beings. By the passing of time, computers have been reduced from a size of room to six of human palm. Computer performs many functions and does variety of jobs with speed and accuracy.

Today, life has become impossible without computers. It is used in Schools, Colleges and has become indispensable part of every business or profession. Research is also an area where computer are playing a major role.

Use of computer in research in science is so extensive that it is difficult to conceive today are search project without computer. Many research studies cannot be carried out without use of computer particularly those involving complex computations, data analysis and modeling. Computer in scientific research is used at all stages starts from study, proposal/budget stage to submission/presentation of findings.

This chapter discusses computers and information technology (IT) in relation to the conduct of health care research. Research is a cyclic process which varies in terms of the number, type and complexity of activities depending upon the question (s) posed, methodology used and outcomes expected. In this chapter, discussion is limited to two major groups of research activities—identifying the background knowledge base for a research project and understanding the data that result from the undertaking.

Given that universities have embraced new information technologies, we must inquire as to the extent these technologies have promoted and/or hindered the higher educational mission. Technology has increased access overall including simultaneous access to a variety of materials from a multitude of sources. One consequence of this eclectic electronic environment is that while access is increasing, comprehension of what is being accessed seems to be decreasing. Previously, the particular disciplinary focus determined the finding tools that would be used for research. These finding tools, in turn, clearly articulated for the user the materials covered (e.g. books, articles, scholarly journals, newspapers, government documents). This shift from an environment where information access was discipline-and/or publication-specific, to one that is amorphous and constantly changing, has put the responsibility for distinguishing among types, formats, quality, and relevancy directly onto the user. This paper will examine the implications for user education both at the university level and beyond.

The importance of digital skills in academic research papers (Atena Editora)

The problem detected is that undergraduate and even postgraduate students still do not have a handle on the digital tools that today are being used for the analysis of information, data, trend analysis through machine learning and this puts young professionals at a disadvantage against those who do understand and use them. To understand the scope, surveys and interviews were carried out, then training was carried out on some platforms and the participants did not know the program or did not have great interest in learning how to use it or see how it could be part of their study style. Digital competences are necessary skills for the development of academic research in the digital age. Today, access to information and digital technologies are essential to carry out quality research. Some of the digital competences that have been detected need to be included by the professional profiles of the graduates are: The ability to carry out effective searches online, that is, students must be able to find and access relevant information for their research effectively and efficiently on the Internet; the ability to assess the quality of information, it is important that students can assess the quality and veracity of the information found online and other digital resources; the ability to organize and store information, students must be able to use digital tools to organize and store information efficiently; the ability to analyze and visualize data, meaning the ability to use digital tools to analyze and visualize data is increasingly important for academic research, and the ability to collaborate online in academic research, collaboration between students from different locations is becoming more common. In the academic life of our students and graduates who are developing their thesis work, which is a purely investigative activity, it is essential to take advantage of digital skills to conclude with a contribution to engineering or science. In this aspect, the scope is for all undergraduate and graduate students of the Continental University. It is concluded then that working with artificial intelligence tools, advanced editing programs and others that allow an agile, secure and traceable search of information sources can be done in less time and thanks to other systems that work collaboratively to share, store, edit and review information in a wide variety of formats allows the researcher to relate more quickly and efficiently with researchers from other places. Thus, it is possible that the research development process is much less complicated and easier to validate and review in order to continue with publications and patent development, among others.

How to Make a Successful Research Presentation

Turning a research paper into a visual presentation is difficult; there are pitfalls, and navigating the path to a brief, informative presentation takes time and practice. As a TA for  GEO/WRI 201: Methods in Data Analysis & Scientific Writing this past fall, I saw how this process works from an instructor’s standpoint. I’ve presented my own research before, but helping others present theirs taught me a bit more about the process. Here are some tips I learned that may help you with your next research presentation:

More is more

In general, your presentation will always benefit from more practice, more feedback, and more revision. By practicing in front of friends, you can get comfortable with presenting your work while receiving feedback. It is hard to know how to revise your presentation if you never practice. If you are presenting to a general audience, getting feedback from someone outside of your discipline is crucial. Terms and ideas that seem intuitive to you may be completely foreign to someone else, and your well-crafted presentation could fall flat.

Less is more

Limit the scope of your presentation, the number of slides, and the text on each slide. In my experience, text works well for organizing slides, orienting the audience to key terms, and annotating important figures–not for explaining complex ideas. Having fewer slides is usually better as well. In general, about one slide per minute of presentation is an appropriate budget. Too many slides is usually a sign that your topic is too broad.

Limit the scope of your presentation

Don’t present your paper. Presentations are usually around 10 min long. You will not have time to explain all of the research you did in a semester (or a year!) in such a short span of time. Instead, focus on the highlight(s). Identify a single compelling research question which your work addressed, and craft a succinct but complete narrative around it.

You will not have time to explain all of the research you did. Instead, focus on the highlights. Identify a single compelling research question which your work addressed, and craft a succinct but complete narrative around it.

Craft a compelling research narrative

After identifying the focused research question, walk your audience through your research as if it were a story. Presentations with strong narrative arcs are clear, captivating, and compelling.

• Introduction (exposition — rising action)

Orient the audience and draw them in by demonstrating the relevance and importance of your research story with strong global motive. Provide them with the necessary vocabulary and background knowledge to understand the plot of your story. Introduce the key studies (characters) relevant in your story and build tension and conflict with scholarly and data motive. By the end of your introduction, your audience should clearly understand your research question and be dying to know how you resolve the tension built through motive.

• Methods (rising action)

The methods section should transition smoothly and logically from the introduction. Beware of presenting your methods in a boring, arc-killing, ‘this is what I did.’ Focus on the details that set your story apart from the stories other people have already told. Keep the audience interested by clearly motivating your decisions based on your original research question or the tension built in your introduction.

• Results (climax)

Less is usually more here. Only present results which are clearly related to the focused research question you are presenting. Make sure you explain the results clearly so that your audience understands what your research found. This is the peak of tension in your narrative arc, so don’t undercut it by quickly clicking through to your discussion.

• Discussion (falling action)

By now your audience should be dying for a satisfying resolution. Here is where you contextualize your results and begin resolving the tension between past research. Be thorough. If you have too many conflicts left unresolved, or you don’t have enough time to present all of the resolutions, you probably need to further narrow the scope of your presentation.

• Conclusion (denouement)

Return back to your initial research question and motive, resolving any final conflicts and tying up loose ends. Leave the audience with a clear resolution of your focus research question, and use unresolved tension to set up potential sequels (i.e. further research).

Use your medium to enhance the narrative

Visual presentations should be dominated by clear, intentional graphics. Subtle animation in key moments (usually during the results or discussion) can add drama to the narrative arc and make conflict resolutions more satisfying. You are narrating a story written in images, videos, cartoons, and graphs. While your paper is mostly text, with graphics to highlight crucial points, your slides should be the opposite. Adapting to the new medium may require you to create or acquire far more graphics than you included in your paper, but it is necessary to create an engaging presentation.

The most important thing you can do for your presentation is to practice and revise. Bother your friends, your roommates, TAs–anybody who will sit down and listen to your work. Beyond that, think about presentations you have found compelling and try to incorporate some of those elements into your own. Remember you want your work to be comprehensible; you aren’t creating experts in 10 minutes. Above all, try to stay passionate about what you did and why. You put the time in, so show your audience that it’s worth it.

How to Make a PowerPoint Presentation of Your Research Paper

• 4 minute read
• 127.9K views

Table of Contents

A research paper presentation is often used at conferences and in other settings where you have an opportunity to share your research, and get feedback from your colleagues. Although it may seem as simple as summarizing your research and sharing your knowledge, successful research paper PowerPoint presentation examples show us that there’s a little bit more than that involved.

In this article, we’ll highlight how to make a PowerPoint presentation from a research paper, and what to include (as well as what NOT to include). We’ll also touch on how to present a research paper at a conference.

Purpose of a Research Paper Presentation

The purpose of presenting your paper at a conference or forum is different from the purpose of conducting your research and writing up your paper. In this setting, you want to highlight your work instead of including every detail of your research. Likewise, a presentation is an excellent opportunity to get direct feedback from your colleagues in the field. But, perhaps the main reason for presenting your research is to spark interest in your work, and entice the audience to read your research paper.

So, yes, your presentation should summarize your work, but it needs to do so in a way that encourages your audience to seek out your work, and share their interest in your work with others. It’s not enough just to present your research dryly, to get information out there. More important is to encourage engagement with you, your research, and your work.

Tips for Creating Your Research Paper Presentation

In addition to basic PowerPoint presentation recommendations, which we’ll cover later in this article, think about the following when you’re putting together your research paper presentation:

• Know your audience : First and foremost, who are you presenting to? Students? Experts in your field? Potential funders? Non-experts? The truth is that your audience will probably have a bit of a mix of all of the above. So, make sure you keep that in mind as you prepare your presentation.

Know more about: Discover the Target Audience .

• Your audience is human : In other words, they may be tired, they might be wondering why they’re there, and they will, at some point, be tuning out. So, take steps to help them stay interested in your presentation. You can do that by utilizing effective visuals, summarize your conclusions early, and keep your research easy to understand.
• Running outline : It’s not IF your audience will drift off, or get lost…it’s WHEN. Keep a running outline, either within the presentation or via a handout. Use visual and verbal clues to highlight where you are in the presentation.
• Where does your research fit in? You should know of work related to your research, but you don’t have to cite every example. In addition, keep references in your presentation to the end, or in the handout. Your audience is there to hear about your work.
• Plan B : Anticipate possible questions for your presentation, and prepare slides that answer those specific questions in more detail, but have them at the END of your presentation. You can then jump to them, IF needed.

What Makes a PowerPoint Presentation Effective?

You’ve probably attended a presentation where the presenter reads off of their PowerPoint outline, word for word. Or where the presentation is busy, disorganized, or includes too much information. Here are some simple tips for creating an effective PowerPoint Presentation.

• Less is more: You want to give enough information to make your audience want to read your paper. So include details, but not too many, and avoid too many formulas and technical jargon.
• Clean and professional : Avoid excessive colors, distracting backgrounds, font changes, animations, and too many words. Instead of whole paragraphs, bullet points with just a few words to summarize and highlight are best.
• Know your real-estate : Each slide has a limited amount of space. Use it wisely. Typically one, no more than two points per slide. Balance each slide visually. Utilize illustrations when needed; not extraneously.
• Keep things visual : Remember, a PowerPoint presentation is a powerful tool to present things visually. Use visual graphs over tables and scientific illustrations over long text. Keep your visuals clean and professional, just like any text you include in your presentation.

Know more about our Scientific Illustrations Services .

Another key to an effective presentation is to practice, practice, and then practice some more. When you’re done with your PowerPoint, go through it with friends and colleagues to see if you need to add (or delete excessive) information. Double and triple check for typos and errors. Know the presentation inside and out, so when you’re in front of your audience, you’ll feel confident and comfortable.

How to Present a Research Paper

If your PowerPoint presentation is solid, and you’ve practiced your presentation, that’s half the battle. Follow the basic advice to keep your audience engaged and interested by making eye contact, encouraging questions, and presenting your information with enthusiasm.
