What is: Z-Alpha - LEARN STATISTICS EASILY
Z-Alpha, often denoted as Zα, is a statistical term that represents the critical value associated with a specified level of significance in hypothesis testing. In the context of a normal distribution, Z-Alpha is used to determine the threshold beyond which we reject the null hypothesis.
