(i) Each score is in lesser difference, it is easy to calculate average than median.
Ex : monthly salary of 5 persons, 10000, 10100, 10200, 10300, 10400 Mean of the scores is 10200.
(ii) If scores have more difference, it is easy to calculate median than mean.
Ex.: Marks obtained by 7 students in Mathematics : 2, 10, 20, 15, 4, 23, 3
Ascending Order :
2, 3, 4, 10, 15, 20, 23
Median =10 but mean is 11.
