Describe the nature of a sample drawn from a population
A demographic variable is a variable that is collected by researchers to describe the nature and distribution of the sample used with inferential statistics. Within applied statistics and research, these are variables such as age, gender, ethnicity, socioeconomic measures, and group membership. Demographic variables are often reported using descriptive statistics. Table 1 of most published research articles contain demographic information regarding the study sample. Demographic variables may also be entered into multivariate models for controlling and confounding effects.
