ETA Squared Calculator
Introduction:
In the realm of statistical analysis, the eta squared calculator plays a crucial role in determining the proportion of variance in a dependent variable that is attributable to an independent variable. This article will guide you through its usage, provide the accurate formula for calculation, and furnish a functional code for a calculator.
How to Use:
Using the eta squared calculator involves simple steps. First, input the sum of squares for the independent variable (SSB) and the sum of squares total (SST) into the designated fields. Once entered, click the ‘Calculate’ button, and the calculator will swiftly produce the eta squared value.
Formula:
The formula for calculating eta squared (η²) is as follows:
Where:
- SSB is the sum of squares between groups (independent variable).
- SST is the sum of squares total.
Example Solve:
Suppose we have SSB=150 and SST=300. Using the formula:
Therefore, the eta squared value is 0.5.
FAQs:
Q: What is eta squared used for?
