Paired Samples T Test Example. The paired sample t test sometimes called the dependent sample t test is a statistical procedure used to determine whether the mean difference between two sets of observations is zero in a paired sample t test each subject or entity is measured twice resulting in pairs of observations. The mean is the difference between the sample means.
The last one paired samples test shows the actual test results. The two means can represent things like. Spss reports the mean and standard deviation of the difference scores for each pair of variables.
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.
To test this we may recruit a simple random sample of 20 college basketball players and measure each of their max vertical jumps. M d 0 step 2. Spss creates 3 output tables when running the test. The paired samples t test in spss statistics determines whether means differ from each other under two conditions.
