- 6What is R2 used for?Indicates how close data is to the fitted regression line
If 0%- model explains none of the variability of the response data
If 100%- explains the variability - 7How do you find the F ratio?Divide the effect variance, by the error variance

- 12What are the values put forth by Cohen (1988) about the level of effect size?If:
d= 0.2 (small)
d= 0.5 (medium)
d= 1.0 - 13What does a larger F-ratio show?There are larger systematic effects present
- 14Why would you use an ANOVA over multiple t tests?To reduce the likelihood of a type 1 error
