May 10, 2021 at 5:52 comment added petyar The way I understand it, a t test would look for a difference in means because it would assume that the data are normally distributed, which is far from the case here. I think maybe a non-parametric test, like a Wilcoxon test, would be suitable on the raw data, but I'm not sure how much.
