what is research study design

The study design used to answer a particular research question depends on the nature of the question and the availability of resources. In this article, which is the first part of a series on “study designs,” we provide an overview of research study designs and their classification. The subsequent articles will focus on individual designs.

A research design is a strategy for answering your research question using empirical data. Creating a research design means making decisions about: Your overall research objectives and approach. Whether you’ll rely on primary research or secondary research. Your sampling methods or criteria for selecting subjects. Your data collection methods.

Research design refers to the overall plan, structure or strategy that guides a research project, from its conception to the final analysis of data. Research designs for quantitative studies include descriptive, correlational, experimental and quasi-experimenta l designs. Research designs for qualitative studies include phenomenological ...

Case study research design. The case study approach in a research design focuses on a detailed examination of a single case or a small number of cases. Cases can be individuals, groups, organizations, or events. Case studies are particularly useful for research designs that aim to understand complex issues in real-life contexts. The aim is to ...

A double blind study is the most rigorous clinical research design because, in addition to the randomization of subjects, which reduces the risk of bias, it can eliminate or minimize the placebo effect which is a further challenge to the validity of a study.

The Research Study Design course provides learners with an introduction to research study design, a detailed overview of scientific inquiry, examples of various research designs, a discussion of data management methods, an introduction to statistical analysis, and sound approaches to optimize the reproducibility of research results.

What is Research Design? Research design can be thought of as the structure of research – it is the “glue” that holds all of the elements in a research project together. There are many different types of designs that you will be introduced to, often having rather exotic-sounding (if not somewhat obscure!) names like ’the nonequivalent ...

Choosing and designing the most appropriate study to address your clinical research problem is paramount in generating the best evidence. This module will introduce some of the more advanced concepts and skills of research design, emphasising how they relate to evidence-based health care. Choos

Specific Types of Research Designs. Single-Sample Repeated Measures: A design method in which the same group is tested at multiple points in time. Giving students an assessment of knowledge the first day of class and giving the same assessment on the last day of class is an example of a research design based on a single-sample repeated measures.
