Descriptive statistics will teach you the basic concepts used to describe data. This is a great beginner course for those interested in Data Science, Economics, Psychology, Machine Learning, Sports analytics and just about any other field.

Statistics for Engineers is called the prior, which is the probability distribution from any prior information we had before looking at the data (often this is taken to be a constant).

This lesson will introduce descriptive, or summary statistics. This is an important concept because when you're working with the data, particularly large data sets.
