Paired Samples T Test Example. The two means can represent things like. M d 0 step 2.
The assumptions underlying the repeated samples t test are similar to the one sample t test. This is relevant since the paired t test is a one sample t test where the data is the differences between the pairs. So before i even go into this particular example let s just make sure we understand the difference between a two sample t test and a paired t test.
So when were talking about either a two sample t test or a two sample t interval for the difference between the mean what we re doing is we re considering two populations.
See the following webpage regarding the confidence interval for the one sample t test. The default null hypothesis for a 2 sample t test is that the two groups are equal. Spss reports the mean and standard deviation of the difference scores for each pair of variables. The last one paired samples test shows the actual test results.
