Calculation Omega

Squared (ώ^{2}) in Excel

Omega squared is calculated with the formula

* (Click Image To See a Larger Version)*

and is implemented in Excel on the data set as follows:

*(Click Image To See a Larger Version)*

An omega-squared value of 0.0732 would be classified as a medium size effect.

Magnitudes of omega squared are generally classified as follows: Up to 0.06 is considered a small effect, from 0.06 to 0.14 is considered a medium effect, and above 0.14 is considered a large effect. Small, medium, and large are relative terms. A large effect is easily discernible but a small effect is not.
