   How do you calculate a Z critical value?

   • In the case of the Z critical value all we need to calculate the critical value is the significance level (the alpha value) for the test. The alpha value reflects the probability of incorrectly rejecting the null hypothesis. The Z critical value is consistent for a given significance level regardless of sample size and numerator degrees.

   What is the Z critical value of Z 01/2?

   • The corresponding z critical values on the outside of the table are -1.64 and -1.65. By splitting the difference, we see that the z critical value would be -1.645. And typically when we use zα/2 we take the absolute value. Thus, z.01/2 = 1.645. We can also use a Critical Z Value Calculator to find zα/2 for some test.
