# Eta Squared Calculator

ANOVA is a statistical collection used to examine the variations between the means of two different groups. An effect size index in ANOVA (Analysis of Variance) is eta squared(η^{2}). The ratio of the variance of an effect to its total varaince is called as Eta Squared. This calculator allows you to find the sum of squares, Mean squares and F (between, within, total) and find eta squared based on it.

### Example

**Number of Rows is 2 , Number of columns is 2. **
Consider the values of matrix

**2 4 **

3 5

#### Step 1 : Sum of Squares

Between = 4

Within = 1

Total = 5

#### Step 2 : DF

Between = 1

Within = 2

Total = 3

#### Step 3 : Mean Squares

Between = 4

Within = 0.5

#### Step 4 : F Calculation

F is 8.

#### Step 5 : Find Eta Squared

η^{2} = 1
