(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 = (1+2+3+4+20)/5 = 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.
