hi all, I’m attempting to analyze data describing week of mortality according to factors of block, plant variety, and pathogen isolate. my qq plot doesn’t look too bad, but my variances fail the levene’s test (p < 0.001). I’ve tried transforming the data a million ways to get it to pass, but it just won’t, even when using Box-Cox. I’ve read differing opinions about whether or not homogeneity actually matters in ANOVA, so I was wondering if you all had any opinion. I have five blocks, three varieties, and six isolates. there is no missing data, if that matters.
