>>90070629t test and such here. test stat is Avgviewers, by(vshojo_status). means a ttest before and after they left. I tested the cumulative affect, means I this is a general t test for all three members NOT individually. the first graph shows that the average viewers can be approximated by a normal distribution, but I also included a Mann-Whitney-U test if the assumption of non normal distributed values is true. As you can see, leaving vshojo decreases your average viewers significantly at a confidence level of 99% (even 99.9%)
