Hi
I'm trying to find a statistical test that can help me compare the means of two dependent groups.
My data:
1: parameter values from white matter region in an in vivo rat brain
2: parameter values from white matter region in the same rat brain, bur after the tissue has been fixated.
I cannot align/register the two brains to each other, so the region I have outlined in vivo is not exactly the same as the region I have outlined in the fixated tissue.
My wish: I would like to compare the means of the two white matter regions.
My suggestion: A paired t-test, but as I know that each pixel value in data set 1 does not exactly correspond to the pixel value in data set 2, the paired t-test is not exactly right to do.
Is there a test of dependent but NOT paired data?
Thank you for your help!
