MathGloss/H/Histogram

A typical histogram
Pulse rates, in beats per minute, were calculated for 192 students enrolled in a statistics course at the University of Adelaide. The first step in creating a histogram is to create a frequency table.

Using the class frequencies (the number of observations in each class interval) shown in the frequency table, the following histogram was created.



Exploring the effect of class interval size
See West's histogram applet for an opportunity to experiment with different class interval sizes.
