the difference score

In the ____ samples t test, the difference scores for each ____ are calculated to use as the data to be analyzed.

Type I

Sample differences scores standard deviation divided by the square root of the sample size are called____

standard error

In the ____, the difference scores for each subject/pair are calculated to use as the data to be analyzed

between- subject/paired samples t test

In the case of related samples, we would use the ____between the pairs of scores for each match as our dependent variable and compare the differences score mean with the difference expected, if there is no difference.
