    Which statistical test to use?




    I have two methods- Method A (old) and Method B (new). Method A is an old algorithm for the company Vungle. Method B is the new algorithm. The daily eRPM (revenue) of the strategy B was on average $0.134 higher than As. To say B is better, statistically, which test should I use?

    I'm between a Paired T-Test, and Welch's T-Test. There are 30 observations of each, and I don't believe I know the variance (at least it wasn't given). So which test should I use? Thank you!

    How do you know there were thirty values in each group, we weren't given that info?


    I would treat it as a one sample t-test compared against zero, though a dispersion parameter is needed to do the calculation.
