Answer 1

(i) While if we take the case of calculating the weight of students in a class, then we should use mean rather than median. In such cases taking median is not suitable.

(ii) If the score of students in a class are 1,2,3,4,20

So if we calculate the mean =

$\frac{1 + 2 + 3 + 4 + 20}{5} = \frac{30}{5} = 6$

Median =3

So, median is better or appropriate measure because 20 is much greater than other numbers and because of 20 the mean has come out to 6.

∴ Its better to take median than mean.
