Linear Regression Test Expectations
A. Explanatory/Response
B. Enter data into R & construct a scatterplot
C. Describe form, direction, & strength of a scatterplot
D. Calculate correlation in R
E. Know all correlation properties from this page.
F. Calculate LSRL in R and be able to fit line to scatterplot
G. Use LSRL to calculate y-hat given an x-value
H. Know how to calculate residuals by hand and using R
I. Know how to construct residual plots in R and how to interpret them.
** NOTE - You do not need to know how to analyze data that is in R. In other words, you don't need to know library, attach, ? commands.. etc..
