I am so lost about what test to use... Help!

#1
I am in the process of comparing the difference in times to complete a task between two groups...

I thought that a two-sample T-test would be best but I am rubbish and keep second-guessing myself! HELP! o_Oo_Oo_Oo_Oo_Oo_Oo_O

How large is your sample size? And what do you mean by "I am rubbish and keep second-guessing myself"?

With kind regards

So in one group, I have 90 cases and in the other, I have 180. I am just not very good with statistics so whenever I use them I have to relearn them and I get very easily confused

t-test with Welch correction (for your sample sizes are very unsimilar, which could cause problems if also variances are unequal) would be my first choice.
