A researcher runs a one-way ANOVA comparing exam scores across 3 teaching methods. SPSS reports Partial Eta Squared = .06 for the teaching method effect. Which interpretation is MOST appropriate?
A
About 6% of the variance in exam scores is explained by teaching method, after accounting for other effects in the model.
B
Teaching method increases exam scores by 6 points on average.
C
There is a 6% chance the null hypothesis is true.
D
The effect is definitely large because .06 is greater than .05.
