↔️ Drag Near Cutoff Line: Moves the vertical F Bound left or right.
🎛️ Drag Graph Canvas Background: Left/Right changes df₁, Up/Down changes df₂.
How to Use the Interactive F-Distribution Visualizer
This interactive F-distribution calculator is an advanced, web-based tool designed to visually explore continuous probability distributions essential for ANOVA testing and regression analysis.
Adjust Degrees of Freedom (df) – Manually type values for the numerator (df₁) and denominator (df₂) or drag your mouse/finger across the background of the F-distribution graph to dynamically morph the skewness of the curve.
Calculate Critical P-Values – Click and drag the vertical red line to alter the F cutoff value. The application will instantly shade the right-tail probability area representing your statistical significance level or p-value.
Export Graphics Intact – Right-click anywhere on the canvas to save or copy the generated chart. The structural metrics (df₁, df₂, F-value, and tail probabilities) are rendered natively into the canvas layer, ensuring perfect data visibility when embedded into reports.
