I am about to perform a 2-way ANCOVA but I reject the null hypothesis in Levene's Test with a p-value of 0.023. See standard deviation and sample sizes below.
I googled up and down and found people saying that: 1) I can still perform the ANCOVA because the smaller group ($n=32$) has the smaller variance, and 2) I should be good to go if the smallest variance is not more than 4 times smaller than the biggest variance--> something like this:
Does somebody here know a citable source for these two claims? They would both save me from going crazy!
Thanks a lot in advance!
