In statistics-speak, we set the significance level, denoted by α, to 0.05. It's a good practice to make this decision before collecting the data and before calculating test statistics. We calculate a test statistic. Our test statistic is 0.750. We find the value from the t-distribution. ...
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-tests calculate t-values, you’re well on your way to u...

Use a paired t-test when each subject has a pair of measurements, such as a before and after score. A paired t-test determines whether the mean change for these pairs is significantly different from zero. This test is an inferentialstatisticsprocedure because it uses samples to draw conclusion...

The paired t test compares the means of two matched groups, assuming that the distribution of the before-after differences follows a Gaussian distribution.
