Give one example of a situation in which
(i) the mean is an appropriate measure of central tendency.
(ii) the mean is not an appropriate measure of central tendency but the medians is an appropriate measure of central tendency.
Solution: (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
So if we calculate the mean
So, median is better or appropriate measure because is much greater than other numbers and because of the mean has come out to
Its better to take median than mean.
