I am doing a research projet and I need to interpret some data. More specifically, I need to compare 10 groups where our treatment worked, and find if one of the group statistically comes out from the rest. Here's the data.

I am wondering what test I should use. I could do a lot of student t tests but then from what I understand the accuracy drops. Would Anova work in this case? Prism doesn't seem to let me do a one way anova with this data right now so I'm not sure I understand how I'd be able to do it.

Thank you so much!
