Question

The ages of children in a scout camp are $13,13,14,15,13,15,14,15,13,15$ years. Find the mean, median and mode of the data.

Answer 1

Arranging the given data in ascending order

$13,13,13,13,14,14,15,15,15,15$

$n=10$

mean$=\frac{4\left(13\right)+2\left(14\right)+4\left(15\right)}{10}=14$ years

As $n$ is even, median$=\frac{4th+5th}{2}$value$=14$ years

$13$ and $15$ both have the highest frequencies of $4$

It is a bimodal set of data.

mean$=14$;median$=14$;mode$=13,15$
