I'd also suggest plotting a wind rose for each month (try openair) to
understand the statistical test results.

Hey
In my data set i have two variables: month (march or april) and wind
direction (N,NE,E,SE,S,SW,W,NW). I have to know if there is a difference in
wind direction between these months. What kind of test statistic should i
use?
Kind regards
Dries David
