Social statistics is the use of statistical measurement tools to study human/social behavior in a social environment. This can be accomplished through drawing a particular group of people, evaluating a particular subset of data obtained about a group of people, or by observation and statistical analysis of a set of data that relates to people and their behaviours. Social scientists use social statistics for many purposes, which include: 1) the evaluation of the quality of services provided to a specific group or by a certain organization, 2) analyzing behaviors of groups of people in their environment and special situations, and 3) determining the wants or needs of people through statistical sampling
