Really? I think we have exactly the same problem in the UK. Granted, my eyes are more susceptible post laser surgery, but headlights are definitely getting brighter and higher as the years go by.
One big difference is that there are lots of reviews for $CommonPosition. With this, you'd have to expect that most reviews are the only one for a given property/landlord
> Unfortunately, if you’ve been observing the p-values, you’ve noticed that most have been very high, and therefore that test is not enough evidence that the tips/threats change the distribution
It doesn't look like these p values have been corrected for multiple hypothesis testing either. Overall, I would conclude that this is evidence that tipping does _not_ impact the distribution of lengths.
