In the formula above, n is the number of students – which is the number of differences. The standard deviation of the differences is sd. We now have the pieces for our test statistic. We calculate our test statistic as: $ t = \dfrac{\text{Average difference}}{\text{Standard Error}}...
t-test statistisc valuecan be calculated using the following formula: t=ms/n−−√t=ms/n where, mis the mean differences nis the sample size (i.e., size of d). sis the standard deviation of d We can compute the p-value corresponding to the absolute value of thet-test statistics...

The effect size for a paired-samples t-test can be calculated by dividing the mean difference by the standard deviation of the difference, as shown below. Cohen’s d formula: d=meanDSDDd=meanDSDD WhereDis the differences of the paired samples values. ...
How to use paired t-test formula Step 1: First, you need to define what your null and alternative hypotheses are. The choices are two-tailed, left-tailed or right-tailed. Step 2: Then, you need to specify your significance level. Typically, you will choose α = 0.05. This is the tol...
