Key Points: Histograms
- A Histogram is a graphical representation of a grouped frequency distribution using rectangles.
-
It is used for continuous grouped data.
-
Class intervals are shown on the X-axis.
-
Frequencies are shown on the Y-axis.
-
Rectangles are drawn without gaps between them.
-
The height of each rectangle is proportional to its frequency.
