# 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?**

**A:** Eta squared is utilized in statistical analysis to quantify the proportion of variance in a dependent variable explained by an independent variable.

**Q: Can eta squared be negative?**

**A:** No, eta squared ranges from 0 to 1, where 0 indicates no effect, and 1 signifies a complete effect.

**Q: Are there other measures similar to eta squared?**

**A:** Yes, other measures include partial eta squared and omega squared, each with specific use cases.

**Conclusion:**

In conclusion, the eta squared calculator is a valuable tool for researchers and statisticians to assess the impact of independent variables on dependent variables. The provided HTML and JS code simplifies the calculation process, ensuring accuracy and ease of use.
