F-Distribution Applet/CalculatorF-Distribution$X sim F_{( u_1, u_2)}$This applet computes probabilities and percentiles for the F-distribution $X sim F_{( u_{1}, u_{2})}$.
Directions:
Enter the numerator degrees of freedom in the $ u_1$ box. Enter the denominator degrees of freedom in the $ u_2$ box.To compute a left-tail probability, select $P(X lt x)$ from the drop-down box, enter a numeric $x$ value in the blue box and press the "Compute" button. The probability $P(X lt x)$ will appear in the pink box. Select $P(X gt x)$ from the drop-down box for a right-tail probability.
To determine a percentile, enter the percentile (e.g. use 0.8 for the 80th percentile) in the pink box, select $P(X lt x)$ from the drop-down box, and press the "Compute" button. The percentile $x$ will appear in the blue box.
On the graph, the $x$ value appears in blue while the probability is shaded in pink.
