Descriptive statistics describe samples and give context to statistical findings
Descriptive statistics play a central role in putting inferential statistical analyses into context. Every research study that uses inferential statistics should have a section presenting descriptive statistics related to the sample. The p-values associated with treatment effects should be interpreted within the context of the measures of descriptive statistics generated in the inferential analyses.
