    The viedo is very good, it crealry explain a important statistical method. I am novice to R and I would say that a lesson that takes 3 or more package to be installed tells us that probably R is not for everyone: every package has its logic, its syntax, and so on, for example when a version change sometimes the syntax is non loger valid, that is probably the case with the error we take in using cld function.

    As for the error we take using cld function: 1) install package multcomp: install.packages("multcomp") 2) load the library multcomp: library("multcomp") 3) change the syntax of the cld function: cld(posthoc[[1]], alpha=.05, Letters=letters). Hope it works for you.

    Hi, my dependent variable is the number of questions answered in a privacy sensitive context (0-19). Can I also use the ANOVA for this count data ?

    If either the Levene's test or the Shapiro Wilk test were not > 0.05, would you not be able to run the two way anova? Is there a non parametric test that could be used?
