To calculate if there is a significant difference in variation between two data-sets. This test is robust when the data is not normally distributed. It calculates the Levene variation test between this column and the comparing column.

- The smaller the p value is the more likely there is a significant difference in variation between the data-sets.
- Develve uses the commonly accepted value of p < 0.05 for significance.
- If the data-sets is normally distributed use the Variation F-test
- For this test is no minimum sample size (power) calculation

- GreenNo significant difference
- YellowSignificant difference

With the W value and the degrees of freedom can the program calculate the p value.

To calculate if there is a significant difference in variation between two or more data-sets. This test is also robust when the data is not normally distributed. It calculates the Levene variation test between the selected columns.

- The smaller the p value is the more likely there is a significant difference of one ore more of the selected data-sets.
- Develve uses the commonly accepted value of p < 0.05 for significance.
- For this test is no minimum sample size (power) calculation

- GreenNo significant difference
- YellowSignificant difference

With the W value and the degrees of freedom the program can calculate the p value out of the F distribution.
