>So, with the drop in relatively low-level police activity, what happened to serious crime in the city? The scientists found that civilian complaints of major crimes dropped by about 3% to 6% during the slowdown.

Is 3-6% a significant enough difference to draw conclusions from?

I wonder what is the normal variation in major crime complaints from one six week window to another?




yeah, it's not like this is a randomized experiment so there might be confounding factors. Observational studies aren't very useful for determining causation in general
