paired ttests and power
... -Assumes that the differences come from a normally distributed population of differences -If there is pariwise correlation of data, the pairedsample t-test will be more powerful than the “regular” t- test -If there is no correlation then the unpaired test will be ...

STAT101: A Review of the Basics
... First we test the null hypothesis that the variances of the two groups are equal. This is done with the F' statistics given at the bottom of the output which shows the probability that the variances are unequal due to chance alone. If the probability (Prob F') is small, usually less than .05, then r ...
