Descriptive Research Descriptive research is a study designed to depict the participants in an accurate way. More simply put, descriptive analysis is all about describing people who take part in the survey. There are three ways a researcher can go about doing a descriptive research project, and they are: Observational, defined as a method of viewing and recording the participants Case study, defined as an in-depth study of an individual or group of individuals Survey, defined as a brief interview or discussion with an individual about a specific topic Descriptive Blog: The 3 Basic Types of Descriptive Research Methods https://psychcentral.com/blog/the-3-basic-types-of-descriptive-research-methods/ Video: Descriptive Research Design https://www.youtube.com/watch?v=jhPWBahCvQM Mixed Methods Research Mixed methods research (Extracted from the article below) is the use of quantitative and qualitative methods in a single study or series of studies. It is a new methodology that is increasingly used by health researchers, especially within health services research. There is a growing literature on the theory, design, and critical appraisal of mixed methods research. However, few papers summarize this methodological approach for health practitioners who wish to conduct or critically engage with mixed methods studies.

A Meta-analysis is an analytical tool for estimating the mean and variance of underlying population effects from a collection of empirical studies addressing ostensibly the same research question. Meta‐analysis has become an increasingly popular and valuable tool in psychological research, and significant review articles typically employ these methods.

In epidemiology, the patient is the community and individuals are viewed collectively. By definition, epidemiology is the study (scientific, systematic, and data-driven) of the distribution (frequency, pattern) and determinants (causes, risk factors) of health-related states and events (not just diseases) in specified populations (neighborhood, school, city, state, country, global).
