How To Find Critical Value On Calculator

T critical value for a left tailed test.

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. These are listed as follows. To find the z critical value on a ti 84 calculator we can use the following function.
