Lucinda used ANOVA to test if there were statistically significant differences between the five conditions of her independent variable. There were 8 participants in each condition. Her obtained F-test (df between = 4, df within = 30) was F = 10.897/3.72 = 2.914, p < .05. When she conducts her tests to know which groups are significantly different, how far apart must the group means be in order to be significantly different?
