Hello Thankyou for the help. kruskal.test(Temp, Roof) is simple but just returns one result for the whole temperature dataset organised by roof.
I want to compare the Temp data for each Roof in each Month. So because i have temperature data on the three roofs for 16 different months then i want 16 separate kruskal.test results., How do i do this?
