Effect sizes can be obtained by using the tests statistics from hypothesis tests, like Student t tests, as well. In case of independent samples, the result is essentially the same as in effect size calculation #2. Dependent testing usually yields a higher power, because the interconnection between data points of different measurements are kept ...

If you use a two-sample t-test as your A/B split test, then typically the sample size (assuming this is what you mean by “number of tests”) required is based on statistical power (as well as significance level and effect size); how to calculate the sample size in this case is described at Power of t Tests Sample size requirements for t-tests

For this example, let’s stick to the two-sided t-test. We can see that the t-statistic, the location parameter and the effect size all changed to negative values. Both the t-statistic (t = -5.823) and the effect size (d = -1.456) suggest that the observed mean is quite far off from what we would expect to see if the null hypothesis were true. The Mann-Whitney U-Test is a test with a wide applicability, wider than the t-Test. Why that?
