Hi. I am trying to analyse the results of my experiment for my diploma. I had 10 different plant medium, 2 different types of plant explants with 6 replications. I cultured plant explants in vitro for 6 weeks, after that time i counted new shoots, which developed from explants. The number of new shoots differentiated due to different plant medium and type of explant. In most cases there wasn't any new shoot or just 1 per 6 replications; but in one case there were 13 new shoots per 6 replications (one medium really stood out).
I wanted to carry out ANOVA test, but the Levene's test failed (the upper picture). Then i transformed the data using log10 + 1 (the bottom picture), but Levene's test failed again. Should i try any other transformation or is the only solution using a nonparametric test?
I have one more question. Can i carry out ANOVA if Levene's test go through but the diagnostic plot shows that residuals are not normally distributed?
Best regards,
Natalija
