About Descriptive Statistics
Descriptive statistics are used to describe the basic features of the data in a study. They provide simple summaries about the sample and the measures. Together with simple graphics analysis, they form the basis of virtually every quantitative analysis of data.
Measures of Central Tendency: Mean, median, and mode tell you where the "center" of your data is.
Measures of Dispersion: Variance and standard deviation tell you how spread out your data is.
