I am running a mann whitney test to compare the mean value between two different groups and for some reason the calculated means are massively incorrect as my data is rank order and can be only scored between 1-12 and my mean values are equaling 22
I am also running a kruscal wallis test to compare the means scores of four groups, however the means are again massively incorrect.
I have 100% sure i have coded the data correctly and 100% sure im running the correct test but for some reason the calculated means are incorrect which is not allowing me to compare data between groups for both test.
Does anyone know why this is happening?????????
