A case study can be defined as a descriptive account of the behavior, history, and other relevant factors concerning a particular individual (Cozby, Bates, 2012).
With the scope of contemporary technology, we are able to access information from various studies that have occurred around the world.

The advantages and disadvantages of self-administered questionnaires are summarized in table 3.6 below: The main advantage of statistics is that information is presented in a way that is easy to analyze, which makes its conclusions easily accessible.

Therefore, it is important for scientists, researchers, and statisticians to recognize that both have their advantages and limitations and choice of method should depend on the circumstances. (2002);The PICO and PEO formats are used commonly in health research and nursing to form a research question. Statistics as a field of study can be divided into two main branches, descriptive and Today, in most research conducted on groups of people, both descriptive and inferential methods are used. So both methods have their limitations and advantages. There are two types of statistics that are used often in research. definition is statistics that describe the data in some way.
