1
Q

A
The strength, direction, and form of the relationship in context of the problem.
2
Q
Conditions for inference about the LSRL
A
- Linearity
- Normality
- Independence
- constant standard deviations of the responses for all x
3
Q
Define “r^2”
A
How much of the variation/change in y is determined by the variation/change in x.
