Question

Explain how to obtain normal scores from Table III in Appendix $A$ when a sample contains equal observations.

Short answer

If two or more samples have the same amount of observations, the normal score can be calculated by treating them as somewhat different from one another.

Step-by-step solution

Given Information

Consider the "data normalcy score."

It is a tool for transforming your data into a typical normal distribution.

Explanation

The raw score's distance from the data's mean value is described by the normal score. It's also known as the $z$-score or standard score.

$z-\text{score}=\frac{x-\mu }{\sigma }$

$x\to$raw score.

If two or more samples have the same amount of observations, the normal score can be calculated by treating them as somewhat different from one another.
