This mathlet shows the graph of the probability density function (pdf) for Student t-distributions with \(df\) degrees of freedom. For reference the standard normal distribution is also plotted.

Graph

• The t-distribution with \(df\) degrees of freedom is shown in blue.
• For reference, the standard normal distribution is shown in yellow.

Controls and readouts

• The \(\boldsymbol{df}\) slider is used to set the degrees of freedom parameter.
• When the mouse is in the graphing window its \(\boldsymbol{x,y}\) coordinates are shown next to the upper right of the graphing window.
