Chapter 14, Problem 15SGA

To determine

To find the mean, median and mode of the given data.

Answer to Problem 15SGA

Mean is $210$ , median is $200$ and mode is $200$ .

Explanation of Solution

Given:

The given data is-

  $250,200,160,240,200$

Calculation:

Arranging the data in the ascending order as follows-

  $160,200,200,240,250$

Finding the mean as follows-

Mean

  $\begin{array}{l}=\frac{160+200+200+240+250}{5}\\ =\frac{1050}{5}\\ =210\end{array}$

Median will be the middle element as the number of terms are odd.

So, the median is 3^rd element and that is $200$ .

The mode is the most frequent occurring element. Here $200$ has occurred most number of times. So the mode is $200$ .
