Question

The weights (in kg) of 8 children are
13.4, 10.6, 12.7, 17.2, 14.3, 15, 16.5, 9.8.
Find the median weight.

Answer 1

ANSWER:
Arranging the weights (in kg) in ascending order, we have:
9.8, 10.6, 12.7, 13.4, 14.3, 15, 16.5, 17.2
Here, n is 8, which is an even number.
Thus, we have:
Median=Mean of ($\frac{n}{2}$)th & ($\frac{n}{2}+1$)th observations
Median weight=Mean of ($\frac{8}{2}$)th & ($\frac{8}{2}+1$)th observations
=13.85
Hence, the median weight is 13.85 kg.
