This app calculates and plots the standard normal distribution frequency and density functions.

One tail, middle, two tail and cumulative density functions can be calculated together with the raw frequency function.

You may enter directly Z values referred to N(0,1), or X values referred to a generic N(m, s).

In case of X values, the values for m=mean and s=standard deviation are also required. If Z values are entered, X values are computed according to m and s and the other way around.

F-Graph also works as a scientific calculator. You may enter the calculation clicking on the buttons of the application pad or directly directly enter the expression as text. Press = to perform the calculation. The calculator supports multiple level of parentheses. A parenthesis is automatically appended when a function button is pressed. You will have then to enter the argument and the closing brace.
