How to find z alpha/2

In statistics, grasping various measures and their applications is essential for making informed decisions. Two often-used measures in statistical analysis are the z-score and z-critical value.

We will delve into these topics section by section.

By the end of this article, you will clearly understand the differences between the Z score and Z value and know when to use each one for optimal statistical analysis.

What is a z-score?

A Z score, also known as a standard score, represents how many standard deviations a data point is from the mean of a set of data.

It provides a way to compare the relative position of a value within a data set, allowing for standardized comparisons among different data sets or within the same data set.

Formula:

The formula for calculating the Z score is:

Z = (X - μ) / σ

Where:

• Z is the z score
• X is the data point
• μ is the mean of the dataset
• σ is the standard deviation
