When talking about statistics as mathematical operations, there are two basic divisions within the field: descriptive and inferential. Descriptive statistics uses graphical and numerical summaries to give a ‘picture’ of a data set. Inferential statistics, which use mathematical probabilities, make generalizations about a large group based on data collected from a small sample of that group. This course focuses on descriptive statistics, and on their use. Source
