7
Which analysis?
Two-way mixed ANOVA

exam number (1, 2, 3, 4, 5)
each student's overall grade in the class
the questions on each exam
exam scores
16
If the sphericity assumption is violated, one option is to use a critical F value based on smaller df values. This is a:
Welch correction
Hotelling-Hoyt correction
Geisser-Greenhouse correction
Spearman-Tukey correction
17

Multicollinearity
18
Which design?

True
False
21
Dr. Leopold would like to study 4 personality surveys and wants to use the fewest participants possible. He should use:

an assumption of the one-way, repeated-measures ANOVA?
