There are three main types of descriptive research methods: observational research, case studies, and surveys. Observational research involves viewing and recording participants, case studies provide an in-depth examination of an individual or group, and surveys involve brief interviews about a specific topic. Mixed methods research combines quantitative and qualitative methods to study a topic. Meta-analysis statistically combines data from multiple studies on a topic to estimate an overall effect. Epidemiology studies the distribution and causes of health outcomes in populations. Longitudinal studies follow a population over time to evaluate the effects of variables on a process.

Research MethodDescriptive 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 participantsCase study, defined as an in-depth study of an individual or group of
individualsSurvey, defined as a brief interview or discussion with an individual about a
specific topicDescriptive Blog: The 3 Basic Types of Descriptive Research

ResearchMixed 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.ORDER NOW FOR ORIGINAL, PLAGIARISM-FREE PAPERSArticle: Using Mixed

statistical technique for combining data from multiple studies on a particular topic. 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.Article: Meta-Analysis in Medical

Introduction)https://www.youtube.com/watch?v=RqmgKg5jTLEEpidemiologyAccording
to the Centers for Disease Control, Epidemiology is the method used to find the causes of
health outcomes and diseases in populations. In epidemiology, the patient is the community
and individuals are viewed collectively. By definition, epidemiology is the study (scientific,

(causes, risk factors) of health-related states and events (not just diseases) in specified
populations (neighborhood, school, city, state, country, global).Article: Epidemiology is a

StudiesLongitudinal Study, an epidemiologic study that follows a population forward over
time, evaluating the effects of one or more variables on a process. If individuals are
followed, it is termed a longitudinal cohort study. If classes—e.g., age classes—are studied,
it is a longitudinal cross-sectional study. Longitudinal studies are the converse (opposite) of
horizontal (parallel) studies.Article Longitudinal
