Critical value - Wikipedia, the free encyclopedia
In differential topology, a critical value of a differentiable function between differentiable manifolds is the image of a critical point. The basic result on critical values is Sard's lemma. The se...

For example, the .25 critical value for a Chi-square with 4 degrees of freedom is 5.38527. This means that the area to the right of 5.38527 in a Chi-square distribution with 4 degrees of freedom is .25.

Probability of exceeding the critical value 0.10 0.05 0.025 0.01 0.001 ... For upper one-sided tests, the test statistic is compared with a value from the table of upper critical values. For two-sided tests, the test statistic is compared with values from both the table for the upper critical value and the table for the...

Probability of exceeding the critical value 0.10 0.05 0.025 0.01 0.005 0.001 ... The most commonly used significance level is = 0.05. For a two-sided test, we compute the percent point function at /2 (0.025). If the absolute value of the test statistic is greater than the upper critical value (0.025), then we reject...

If you collected data from 27 pairs, the degrees of freedom would be 25. Use the critical value table to find the intersection of alpha .05 (see the columns) and 25 degrees of freedom (see rows).
