A researcher studying reaction times across three experimental conditions notices that reaction times cannot be negative and typically have a right-skewed distribution. She has 25 observations per group. Before conducting ANOVA, she applies a log transformation to the data. The transformed data show improved normality, but now group variances are 0.08, 0.15, and 0.32 respectively. The F-test on the transformed data yields p = 0.031. What is the most appropriate interpretation?
