Histogram

Histograms show frequencies of a single variable grouped into bins or frequency ranges on the x-axis. The y-axis of the histogram shows the frequency count or percentage.

• A large bin size can obscure the data.

• Adjust the size of the bins to best reveal the shape of the frequency distribution.
