Draw a histogram representing the following data:
Class interval600−640640−680680−720720−760760−800800−840Frequency184515328817163
In the given frequency distribution the first class interval is 600 - 640. Therefore, the scale on x - axis starts as 600. For this in general, a kink or a zig- zag curve is drawn near the origin to tell that the graph is drawn to scale beginning at 600 and not at the origin itself.
Therefore, we get the required histogram as below:
