statistical test of normal and non-normal distributed data

44 Views Asked by At

I have 2 samples of data. The first sample is the precision of the first algorithm A for 25 test cases and the second sample is precision for 25 test cases of second algorithm named B. I test both samples and first is normal distributed but second is non-normal distributed. (I check it with QQ plot, lillietest and shapiro-wilk test in R language).

Can I test this two samples with different distribution for example do they have an equal mean? If yes, which test should I use in this case?
