Regression Analysis

Question 1

Goodness-of-fit

Answer 1

R2 = explains the variance in the DV for the model => model fit
H0 => R2=0
HA => R2 >0
Effect sizes 
Small - 0.02
Medium - 0.13
Large - 0.26

Question 2

ANOVA table

Answer 2

F-test => overall significance of the model
F value = p value, should be >0
Significance <0.05

Question 3

Coefficient table

Answer 3

B-value = quantify relationship between DV and each predictor
T value tests wether the b value is significantly different from zero.
