DESCRIPTIVE STATISTICSDescriptive statistics is statistical tools or techniques used to describe a sample or a population. Descriptive statistics reduce large data into a simpler summary. For example, a mean, median or mode is a descriptive statistic. Descriptive statistics describe patterns and general trends in a data set. In most cases, descriptive statistics are used to examine or explore one variable at a time. However, the relationship between two variables can also be described as with correlation and regression. Descriptive statistics describe the basic features of the data gathered from an experimental study. Descriptive statistics provide simple summaries about the sample and the measures. With simple graphics analysis, they form the basis of virtually every quantitative analysis of data.

Descriptive statistics describe patterns and general trends in a data set. Descriptive statistics are used to examine or explore one variable at a time. The relationship between two variables can also be described as with correlation and regression.
