A histogram is a type of bar chart, used predominantly
for continuous variables. Histograms can be used to depict how measurements
vary from the mean value and can help to identify the cause of problems
in a process by the shape of the distribution as well as the width (deviation)
of the distribution.
The main difference
between a histogram and a bar chart is that the frequency in a bar
chart is represented by the height of the bar, whereas for a histogram
the frequency is represented by the area of the bar.
