Study Design

Study design refers to the plan or strategy developed by a researcher to answer a specific research question. It outlines the methods and procedures that will be used to collect and analyze data, as well as the type of data that will be collected. A well-designed study is essential for ensuring that the results are valid, reliable, and generalizable to the population of interest. The study design should take into account the research question, the type of data that will be collected, the sample size, the sampling method, the data collection instruments, the data analysis techniques, and the ethical considerations. There are various types of study designs, including experimental, quasi-experimental, observational, cross-sectional, longitudinal, and case-control studies.
