T Test Chart. The results are significant if the t value is greater than the value in the cell. The analysis will provide the t value test statistic and the significance the probability the difference between the groups is due to chance rather than the predictor variable.

One sample t test not displayed in the figure unpaired two sample t test displayed in the figure paired sample t test displayed in the figure as mentioned the differences that make these t tests different from the other tests are the assumptions of our experiment. Social scientists use spss statistical package for the social sciences to conduct t tests.
Below given is the t table for you to refer the one and two tailed t distribution with ease.
There are three types of t test. It can be used when the population standard deviation σ is not known and the sample size is small n30. Typically they are used instead of the corresponding z tests when the the population standard deviations are not known. Below given is the t table for you to refer the one and two tailed t distribution with ease.
