L8 - Repeated Measures ANOVA

Question 1

When do you use a repeated measures ANOVA?

Answer 1

Design - within-subjects / repeated measures design
IV - examines differences across 3 or more levels
DV - continuous data (interval or ratio e.g., reaction time, IQ score)

Question 2

What assumptions are needed for repeated measures ANOVA?

Answer 2

Data should be normally distributed

Question 3

What does a repeated measures ANOVA do?

Answer 3

Tests the null hypothesis that means are equal across different conditions

Question 4

How do you calculate a repeated measures ANOVA?

Answer 4

Compares variance between conditions with variance within conditions using the F value

Question 5

What’s a High F value?

Answer 5

Indicates large variance between conditions and small variance within conditions (likely significant)

Question 6

What’s a Low F value?

Answer 6

Indicates small variance between conditions and large variance within conditions (likely non-significant)
