# Comparing whether there is a significant difference between 3 numbers. Help please!!

Hi,

So I have lots of participants for whom I have created a score for on three levels. For each participant, I am trying to find out whether there is a significant difference between the three numbers. I was thinking a one way ANOVA but as I'm doing one participant at a time, I'm not if this is correct, and whether I would need an independent variable for this to work?

It's probably really simple - maybe it doesn't even require a test but instead just comparing means? I'm using spss so any help would be greatly received.

So in sum I have 3 numbers A, B, C - and want to know if there is a significant difference between them and if so where this lies.

Thank you!

Seems like a paired samples t-test would work, too. Compare A to B, A to C, and B to C.
