# Whether to perform a 3 by 2 repeated measures ANOVA or three separate paired t-tests?

I have $2\times 3$ repeated measures design.

• 2 conditions(a and b)
• 3 intensities (low, medium and high).

I am concerned only with the a to b differences at the corresponding intensity. For example I would like to compare:

• A low and b low
• A medium and b medium
• A high and b high.

I am not concerned with comparing A low to A medium to A high as physiologically we know that they are different and it does not answer my research question. I don't care about how the 2 variables interact, but I may be wrong. My inclination is to say the paired T -tests are fine as

Should I perform 3 paired t-tests for the comparisons of interest or a $2\times3$ Repeated measures ANOVA?
