Spss T Test Output. First off note that there s only a small difference between our sample means. Paired samples t test output.
Spss output for an independent samples t test. Spss annotated output t test single sample t test. Spss reports the mean and standard deviation of the difference scores for each pair of variables.
Fortunately we rarely need this formula.
Input variables used in the variable view menu. Either jasp or excel readily computes a t test with cohen s d for us. The last one paired samples test shows the actual test results. The problem with outliers is that they can have a negative effect on the independent t test reducing the validity of your results.
