Q. 7.     The runs scored by two teams A and B on the first 60 balls in a cricket match are given below:


              Represent the data of both the teams on the same graph by frequency polygons. [Hint : First make the class intervals continuous.]

Answers (1)


The given data is not continous we therefore modify the limits of the class intervals as well to make the class intervals continous.

To make the frequency polygon we first modify the table as follows

\\Class\ marks= \frac{Upper\ limit\ of\ class\ interval+Lower\ limit\ of\ class\ interval}{2}

To make the frequency polygon we mark the number of balls on the x-axis and the runs scored on the y-axis.

The representation of the given information in the form of frequency polygon is as follows.
