T Test Tables. A t test can only be used when comparing the means of two groups a k a. When to use a t test.
This table is used to find the ratio for t statistics. The acquired probability is the t curve area between the t distribution ordinates i e the given value and infinity. The t table stands for the critical values of t distribution.
The column heading for 2 14479 is 0 025 and the column heading for 2 62449 is 0 01.

The t test is a parametric test of difference meaning that it makes the same assumptions about your data as other parametric tests. To calculate the score for a t distribution find out the df that is the degrees of freedom.
