# Topic - Bentley University GR521

GR521 is a graduate Managerial Statistics course at Bentley University. The description from the course catalog can be found here.

Mathematical topics include random variables, discrete and continuous probability distributions, confidence intervals, hypothesis testing, single-variable linear models, and optionally advanced topics such as data mining, time permitting.

## Basics
