App Description

In probability theory and statistics, the F-distribution is a continuous probability distribution.

The F-Distribution Function Calculator calculates the F-Distribution Cumulative Probability associated with a f value and two Degrees of Freedom.

The F-Distribution Function Calculator also displays a graph for the generated F(x) values from the x random variable and the df(1) and df(2) Degrees of Freedom input variables and displays a table of the graphed values.

The graphs are touch enabled graph. Upon touching the graph a vertical line appears. Move the vertical line to the left or right to display the point x/B(x,y)

The horizontal x-axis displays x values. The vertical y-axis plots a range of either the x-increment and y-increment values

Horizontal Max and Min dashed lines display the Maximum and Minimum values.
