## How do you summarize data using descriptive statistics?

What statistics are used to summarize data?

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.

### Which measures are used for descriptive analysis of data?

Descriptive techniques often include constructing tables of means and quantiles, measures of dispersion such as variance or standard deviation, and cross-tabulations or “crosstabs” that can be used to examine many disparate hypotheses.
