Q.6.117 - Elementary Statistics

Question

Explain why assessing the normality of a variable is often important.

Step-by-Step Solution

Answer

The variable's normalcy is significant.

A random variable's normality is a quality of a normal distribution-distributed random variable.

Step 1: Given Information

Consider the concept of "variable normalcy."

Step 2: Explanation

Many variables are normally distributed or nearly normally distributed in most cases.

These contain both measurement and non-measurement factors.

It is relatively simple to apply statistics while working with the normalcy of the variable.

We'll use this to figure out what kind of statistical test we can use in inferential statistics.

Only normal or approximate normal distributions pass the statistical test.
