Hi everybody, I'll go directly to the point. I did an experiment in which I used electrical stimulations. The stimulation is defined by 2 parameters, pulse and frequency. I used 3 different frequencies (20,70,120) and 4 different pulses(100,200,300,400). Each pulse/frequency combination was given 3 times in randomized order to the subject I have 16 subjects involved in the study. My NULL hypothesis is that there is not difference among different combinations. I cannot find a way to implement it by hand (also using a software would be ok). Do you have any hints? Thanks in advance! Andrea

Hi MAthman, Thanks for your reply. Difference in using a combination pulse/frequency instead of another one.

The question I asked is not the difference in your input, but what is the output that shows a difference.
