From data to ANOVA

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.
