I have a quick question about what kind of analysis to use. I have been out of the stat game for a while and need a refresher. I am doing a research project measuring a parameter on different types of products. For example, I have four products with five data points each. An example data set is below:
Product A - 150, 152, 146, 144, 149
Product B - 143, 142, 138, 145, 136
Product C - 124, 121, 128, 129, 125
Product D - 161, 156, 158, 166, 155
The question is does product A differ significantly from B? from C? from D? Also, is B significantly different from C? from D? etc..
I appreciate any help!
