Normal Distribution graph Folded Normal Distribution graph


The experiment simulates a random variable \(X\) with the normal distribution with mean \( \mu \) and variance \( \sigma^2 \). Random variable \( Y = |X| \) has the folded normal distribution with parameters \(\mu\) and \(\sigma\). On each run, the applet shows the normal variable in the graph on the left. The folded normal distribution is shown in the graph and table on the right. As the experiment runs, the empricial density and moments are shown in this graph and recorded in this table. The parameters \( \mu \) and \( \sigma \) can be varied with the input controls.
