Histogram App

Histogram
Data Axis

Description

Click on the lower horizontal axis to select data points in the interval \([a, a + w]\). The points are shown as red dots on the axis and are recorded in the data table. The histogram graph and histogram table show the cooresponding histogram for the partition of \([a, a + w]\) into \(n\) classes of width \(w / n\) each. The type of histogram graph (frequency, relative frequency, or density) can be selected with the list box. The number of classes \(n\) can be varied with the input control. The domain endpoint \(a\) and width \(w\) can also be varied with input controls; varying these parameters causes a reset.
