1. A histogram is a bar chart that displays a frequency distribution. It is constructed as follows:
- The class frequencies are shown on the vertical (y) axis (by the heights of bars drawn next to each other).
- The classes (intervals) are shown on the horizontal (x) axis.
- There is no space between the bars.
From a histogram, we can see quickly where most of the observations lie. The shapes of histograms will vary, depending on the choice of the size of the intervals.

It is similar to a histogram but the bars are replaced by a line joined together. It is constructed in the follo
