Regression

 

Most of the students in AP Statistics courses have seen linear regression in earlier math courses. So while I have a good explanation of the procedures and the meaning of the coefficient of correlation (r) and determination (r2), I don’t spend that much time on it. Rather than a bunch of small problems, there are several worksheets with problems with multiple parts. Also, in this folder, there is a good explanation of the procedures to recognize and perform exponential and power regression with a packet of problems.
