Research in the social sciences presents a different set of issues than those in medical research  and can involve issues of researcher and participant safety, empowerment and access to justice.

Descriptive statistics usually involve measures of central tendency mean, median, mode and measures of dispersion variance, standard deviation, etc.
Ethnographers spend time interacting with research participants and gleaning data on lifestyle, values, culture influence and consumer purchases.Descriptive science is a category of science that involves descriptive research; that is, observing, recording, describing, and classifying phenomena.
Descriptive research is sometimes contrasted with hypothesis-driven research, which is focused on testing a particular hypothesis by means of experimentation. Descriptive statistics are used to describe the basic features of the data in a study.
