Interpreting T Test Results. Interpret the results see below. This tells us the data that was used in the two sample t-test. For 1 check Enter mean SD and N For 2 label your groups and enter data. Heres how to interpret the results of the test.
The independent-samples t test is what we refer to as a robust test. We need to find the complement the area to the left of t Stat to use it for the left tail test here. In this case we used the vectors called group1 and group2. T-test Stata Annotated Output The ttest command performs t-tests for one sample two samples and paired observations. These results will tell us if the Means for the two groups were statistically different significantly different or if they were relatively the same. N is group size.
A i - B i.
This is the degrees of freedom associated. Along with this as usual are the statistic t together with an associated degrees-of-freedom df. Because the t Stat is positive the Excel one-tail p-value is for the right tail test which is the area under the curve above to the right of the t Stat of 1867. T degress of freedom the t statistic p p value. If n 1 n. Now that we have a row to read from it is time to look at the results for our T-test.
