How about how the weather condition differences in different areas might affect crime rates? Is it easy to mug people when it’s 10 below zero out?

This is actually a great illustration of statistical power. Data over long periods of time clearly show seasonality of crime, with it increasing during the summer (we're not 100% sure why but there are theories). However they can isolate this effect statistically and remove it from data. They do the same thing for numerous other variables.
You're also arguing that one of the cornerstones of modern business is invalid, like every corporation that does this with data is retarded and they just aren't in on it like you are lol. Somebody go to the business analysts convention and tell them
