I have a variable namely INSULIN, and I want to test the significance of means using T test. The original data had some outliars and was not normally distributed. I did log transformation, and it followed normality which I checked using Kolmogorov-Smirnov test. See below table of INSULIN and Log transformed INSULIN.
Group Statistics
Type N Mean Std. Deviation Std. Error Mean
INSULIN_Log_Transformed Cases 74 2.4006 0.56882 0.06612
Controls 196 1.9629 0.73320 0.05237
INSULIN Cases 74 13.0678 8.61817 1.00184
Controls 196 9.5318 8.88716 0.63480
After applying T test for log transformed data. Mean difference was significant. Now I am confused, which means I have to report. If I have to report transformed means, how to do that?
