Partial eta-squared is a measure of variance, like r-squared. It tells us what proportion of the variance in the dependent variable is attributable to the factor in question. You can get these measures by choosing the 'Estimates of effect size' option when setting up an ANOVA.
For example, if your radius was 6 cm, your radius squared would be 36 cm squared. 4. Multiply the result you get from Step 3 by pi. (Use this also in Finding the Area of a Sector).1  If the instructions say leave in terms of pi or exactly, then just stick the pi onto your answer (for example, the area of the circle = Ï36 cm^2.) If you just round it to 3.14, it's not at all exact.or example, if your radius was 6 cm, your radius squared would be 36 cm squared. 4. Multiply the result you get from Step 3 by pi.
