How To Hand Calculate A 3 Sample Levene Test

The Levene test is a statistical test used to assess the equality of variances. Hand calculating a 3 sample Levene test is crucial for understanding the assumptions of many statistical tests. Let’s dive into how to do it.

1. Enter the values for the three samples.
2. Click ‘Calculate’.
3. View the results and chart below.

The Levene test is based on the following formula:

… (detailed explanation of the formula and methodology) …

Example 1: Three samples of heights (in cm)

Sample 1	Sample 2	Sample 3
165	170	168
172	168	170
168	175	165

Comparison of Levene test results

Test	Sample 1 & 2	Sample 1 & 3	Sample 2 & 3
Levene	0.053	0.021	0.087
p-value	0.819	0.884	0.768

• Always check the assumptions before performing a Levene test.
• Consider using a non-parametric test if the assumptions are not met.
