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!
Here you can quickly determine the critical value (s) for two-tailed tests, as well as for one-tailed tests. It works for most common distributions in statistical testing: the standard normal distribution N (0,1) (that is when you have a Z-score), t-Student, chi-square, and F-distribution. What is a critical value?
11 Νοε 2023 · For a test using a 99% confidence level (e.g. α = 0.01), the z critical value is 5.576. And so on. To find the z-score for a given alpha/2, also known as za/2, you can use a standard normal table to look up the probability associated with the given alpha/2.
