2×3 Factorial Design Analysis Calculator
Introduction & Importance
2×3 factorial design analysis is a powerful statistical tool used to analyze the effects of two factors, each with three levels, on a response variable. This calculator simplifies the process, allowing you to perform complex analyses with ease.
How to Use This Calculator
- Select the levels for each factor.
- Click the “Calculate” button.
- View the results and chart below.
Formula & Methodology
The formula for 2×3 factorial design is Y = μ + αA + βB + (αβ)AB + ε, where Y is the response variable, μ is the overall mean, α and β are the effects of factors A and B, (αβ) is the interaction effect, and ε is the error term.
