Formula of paired samples t-test 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 ...
Paired sample t-test Now let’s apply the paired sample t-test on data set by usingt.test()function. Set the value forformulaargument as score is separated by time. Inalternativeargument set the value of alternative hypothesis as“two.sided”in this case for two tailed hypothesis. Themuarg...
Step 6:Use the conclusion of the t-test to give an interpretation in the context of the setting of the specific problem. Paired t test example Question: Assume that you have the following sample of paired data. Sample 1Sample 2Difference = Sample 1 - Sample 2 ...

Formula The paired t-test statistics value can 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 ...
The formula shows the sample standard deviation of the differences as sd and the sample size as n. The test statistic is calculated as: [Math Processing Error]t=μdsn We compare the test statistic to a t value with our chosen alpha value and the degrees of freedom for our data. In ou...
