9 Σεπ 2020 · Whenever you come across the term zα/2 in statistics, it is simply referring to the z critical value from the z table that corresponds to α/2. This tutorial explains the following: How to find zα/2 using a z table. How to find zα/2 using a calculator. The most common values for zα/2. Let’s jump in! How to find zα/2 using a z table.
Standard Normal Cumulative Probability Table z 0 Cumulative probabilities for NEGATIVE z-values are shown in the following table: z .00 .01 .02 .03 .04 .05 .06 .07 ...
Using two Z tables makes life easier such that based on whether you want the know the area from the mean for a positive value or a negative value, you can use the respective Z score table. If you want to know the area between the mean and a negative value you will use the first table (1.1) shown above which is the left-hand/negative Z-table.

T-2 • Tables Table entry for z is the area under the standard normal curve to the left of z. Probability z TABLE A Standard normal probabilities z.00 .01 .02 .03 ...
Z α/2 - the Z-value where p(x ≤ Z α/2) = α/2, left critical value of the two-tailed test. Z 1-α/2 - the Z-value where p(x ≥ Z 1-α/2) = α/2, right critical value of the two-tailed test. Example, Inverse z-table: Row number 6 (excluding the header)
