Paired T Test Test Statistic Formula. The procedure of the paired t test analysis is as follow. S is the standard deviation of d.
Calculate the t statistic which is given by t d se d. This will give the p value for the paired t test. We make a practical conclusion to consider exams as equally difficult.
We compare the value of our statistic 0 750 to the t value.
Use tables of the t distribution to compare your value for t to the t n 1 distribution. Use tables of the t distribution to compare your value for t to the t n 1 distribution. Under the null hypothesis this statistic follows a t distribution with n 1 degrees of freedom. The procedure of the paired t test analysis is as follow.
