Types of Research Methodology

1. qualitative research methodology.

Qualitative methodology focuses on understanding human experiences, behaviors, and social phenomena. It uses non-numerical data and is often exploratory.

Subjective and descriptive.
Data collected through interviews, focus groups, or observations.
Analyzes themes, patterns, and narratives.
Example: A study exploring teachers’ perceptions of remote learning challenges during the COVID-19 pandemic.

2. Quantitative Research Methodology

Quantitative methodology focuses on measuring and analyzing numerical data to test hypotheses or answer research questions. It is often used for studies requiring statistical analysis.

Objective and structured.
Data collected through surveys, experiments, or secondary datasets.
Statistical methods used for data analysis.
Example: Examining the relationship between study hours and academic performance among high school students.

3. Mixed Methods Research Methodology

Mixed methods combine qualitative and quantitative approaches to provide a comprehensive understanding of a research problem.

Integrates numerical data with detailed narratives.
Offers both breadth and depth in analysis.
Often uses sequential or concurrent designs.
Example: Investigating how healthcare workers perceive telemedicine (qualitative) and evaluating patient satisfaction scores (quantitative).

4. Descriptive Research Methodology

Descriptive research aims to describe characteristics, phenomena, or trends in a specific population or setting.

Non-experimental.
Data collected through surveys, case studies, or observations.
Focuses on “what” rather than “why” or “how.”
Example: Surveying college students to understand their preferred learning platforms.

5. Experimental Research Methodology

Experimental research investigates cause-and-effect relationships by manipulating variables and observing outcomes.

Involves control and experimental groups.
Uses randomization to reduce bias.
Common in natural and social sciences.

2. Knowing the Guidelines Inside Out

Before writing your methods section, study the author's instructions for your target journal. Follow the guidelines meticulously. For instance, you might need to change the section heading from “Materials and Methods” to “ Patients and the Method ,” depending on the journal. Some journals may prefer not to disclose the names of institutions in open-label reports. You might also need to adhere to specific style guides, like the APA format. Using standardized checklists for different study types for biomedical research can help ensure you cover all essential details.

3. Weaving a Cohesive Narrative

The experiments in your methods section should be presented logically to help readers understand the development of your study. Organizing methods chronologically is effective. For a clinical trial, you might start with the study’s setting and timeline, then detail patient recruitment, study design, randomization, group assignments, interventions, and data collection and analysis techniques.

4. Aligning with the Results

To enhance readability, align the order of your methods with the results. This coherence will guide readers through your findings more smoothly.

5. Adding Clarity with Subheadings

Break down the methods section using subheadings for each experiment. This structure aids readers in following along. You can use the specific objective of each experiment as a subheading or the experiment's name if applicable.

6. Details, Details, Details

Include every detail you considered when designing the study or collecting data, as minor variations can impact results and interpretation. For outcome measures, provide information on validity and reliability and cite existing literature to support these measures. Describe materials, equipment, or stimuli used, and don’t forget to mention sample size estimation and potential calculation if relevant.

7. Ethical Considerations

Address ethical approval early in the methods section. Specify whether your study was approved by an ethics committee or institutional review board and whether you obtained informed consent from participants or guardians.

8. Specifying Variables Clearly

Identify control, independent, dependent, and extraneous variables that might influence your study’s results. For example, if your research involves teaching methods, prior knowledge of the topic could be an extraneous variable.

9. Detailing Statistical Analysis

Defining Your Participants with Precision

When detailing your Methods section , clarity is critical. Start by describing your sample like this: "We recruited 879 adults, aged 18 to 28, with 56% identifying as female. All participants had completed a minimum of 12 years of education. We obtained ethical approval from the university's board and recruited participants online through Amazon Mechanical Turk (MTurk). We targeted a geographically diverse group from the Midwest using a screening survey. Each participant received $5 upon completion."

Calculating Sample Size and Ensuring Power

Determining your sample size is crucial. Explain it clearly: "Using a sample size calculator, we determined that at least 783 participants were needed to detect a correlation coefficient of ±.1 with 80% power and a significance level of .05."

Outlining Your Materials

Describe the tools you used in your study. For example: "Our primary outcome measures were religiosity and trust in science. Religiosity refers to involvement in religious traditions, while trust in science reflects confidence in scientific research. We also examined if gender and parental education levels predicted religiosity."

Measuring Religiosity

Explain how you measured your variables: "We assessed religiosity using the Centrality of Religiosity scale (Huber, 2003), which includes 15 questions across five subscales. An example item is, 'How often do you feel that something divine intervenes in your life?' Responses range from 1 (very often) to 5 (never), with an internal consistency of .83."

Assessing Trust in Science

Describe your other measures similarly: "We measured trust in science using the General Trust in Science index (McCright et al., 2013). This consists of four items rated on a scale from 1 (completely distrust) to 5 (completely trust). An example question is, 'To what extent do you trust scientists to produce unbiased and accurate knowledge?' The index has an internal consistency of .8."

Detailing Your Procedure

Walk readers through your process: "Participants completed the survey online via Qualtrics, which included demographic questions, the Centrality of Religiosity scale , an unrelated anagram task, and the General Trust in Science index. We included the filler task to prevent priming effects, and an attention check was embedded within the religiosity scale."

Analyzing Your Data

Finally, explain your analysis methods: "We used Pearson's correlation coefficient to assess the relationship between religiosity and trust in science. A t-test evaluated the significance of the correlation. We conducted multiple linear regression for the secondary hypothesis to see if parental education and gender predicted religiosity."

Here are various ways to structure the methods section of a research paper. Your choice will depend on your field, research design, and how you want to communicate your process.

1. IMRAD Format: The Classic Approach

Widely used in science and medical research , this format breaks down the methods into clear subsections:

Participants

Provide details about who was involved, including demographics and how they were chosen.

Materials/Measures

Describe the tools, tests, or questionnaires used.

Outline the steps taken, including any experimental changes.

Explain the methods for statistical or qualitative analysis.

2. Chronological Format: Step-by-Step Guidance

This approach works well for studies that follow a sequence, such as those in social sciences or historical research. Organize the section by the order of each method, specifying timing and duration for phases like data collection.

3. Thematic Organization: Grouping by Themes

This format is ideal for qualitative studies. It groups methods by themes, and it's advantageous in ethnographic research. You can explain data collection and analysis by theme, showing how each area was explored.

4. Comparative Approach: Juxtaposing Methods

Use this format for studies comparing two or more methods, populations, or locations. Describe each method separately, then explain the reasoning behind the comparison and how you conducted it.

5. Subsection Approach: Handling Complexity

Break the methods into subsections for complex studies like mixed methods or engineering research. Describe quantitative and qualitative methods separately and include a section on how these data types were integrated.

6. Diagrammatic Format: Visualizing the Process

Use a flowchart or diagram to summarize your process in fields like engineering or biomedical science. Follow this with detailed explanations of each step, which is helpful if your protocol is complicated.

7. Protocol-Based Format: Sticking to the Script

In clinical trials or laboratory studies, detail the specific protocols or procedures followed. Cite published protocols if applicable, and describe interventions, controls, and how blinding or randomization was handled.

8. Case Study Format: Focusing on Specifics

For case studies, begin with the selection and background of each case. List your data sources, then describe how data was collected and analyzed, often comparing across cases.

Choose the format that best suits your study and communicates your methods to readers.
