Topic - Bentley University MA214
MA214 is an undergraduate statistics course at Bentley University that builds on the basic managerial statistics course taken by all students. The description from the course catalog can be found here.
It covers hypothesis tests, analysis of variance, multiple regression, and contingency tables.
