How to find the critical value of a statistic?
Determine the critical value by finding the value of the known distribution of the test statistic such that the probability of making a Type I error — which is denoted α (greek letter "alpha") and is called the " significance level of the test " — is small (typically 0.01, 0.05, or 0.10). Compare the test statistic to the critical value.
How is the value of T calculated in two tailed students?

How is the critical value of a two tailed test determined?
For a given alpha value "a," the critical value in a two-tailed test is determined by running the formula (1-a)/2 and then looking up the result on a Z-table Step 1 Subtract the alpha value from 1. The alpha value is expressed as decimal less than one.
