Which of the following shows the correct histogram for the given data:
Class interval20−2525−3030−3535−4040−4545−50Frequency3024522846100
In the given frequency distributing the first interval is 20 - 25. Therefore the scale on x axis starts at 20. For this, a kink or zig - zag curve is drawn near the origin to tell that the graph is drawn to scale beginning at 20 and not at the origin.
Therefore, we get the required histogram as below:
