Question

The table shows the Distribution of the Scores obtained by 155 shooters in a shooting competition.

$\begin{array}{cc}\text{Scores}& \text{No. of shooters}\\ 0-10& 10\\ 10-20& 12\\ 20-30& 15\\ 30-40& 8\\ 40-50& 20\\ 50-60& 24\\ 60-70& 7\\ 70-80& 11\\ 80-90& 30\\ 90-100& 18\end{array}$

Use a graph sheet to draw the Histogram for the distribution.

The mode as seen in the graph is ___

Answer 1

As we can see from the graph , the modal class is 80 - 90

When we extend the points to connect them as shown in graph , the point of intersection shown as P when dropped on Q on the x - axis gives the mode.

The mode as seen from the graph is 86
