Having a large amount of data is often beneficial in terms of generalization (extending results from a sample to the corresponding population), but in its raw form, it is very difficult to draw conclusions from. Descriptive statistics provide summaries of the data, and help us make initial inferences that are as accurate as possible. They also form the building blocks for the analyses used to test hypotheses and answer research questions.
