Histograms With Frequency Density
Akopọ
A histogram looks like a bar chart, but when the class widths are unequal a fair picture needs the bars' areas, not their heights, to show the frequencies. The height then becomes the frequency density.
In this lesson you will draw and interpret histograms with unequal class intervals using frequency density.

Histograms, Frequency Polygons, and Time Series Graphs
For most of the work you do in this book, you will use a histogram to display the data. One advantage of a histogram is that it can readily display large data sets. A rule of thumb is to use a histogram when the data set consists of 100 values or more. A histogram consists of contiguous (adjoining)
