In statistics, t-tests are a type of hypothesis test that allows you to compare means. They are called t-tests because each t-test boils your sample data down to one number, the t-value. If you understand how t-
At–Testin statistics is a hypothesis testing method that facilitates the comparison of the results (more specifically, the means) of two scenarios. These tests are termed “t-Tests” because they boil the sample data down to one number called the t-value. ...

The paired t test compares the means of two matched groups, assuming that the distribution of the before-after differences follows a Gaussian distribution.
We can compute the p-value corresponding to the absolute value of the t-test statistics (|t|) for the degrees of freedom (df): df=n−1df=n−1. If the p-value is inferior or equal to 0.05, we can conclude that the difference between the two paired samples are significantly differ...
