Ex: Marks of a student in 7 subjects:
10,35,90,78,55,23,14
Mean = (10 + 35 + 90 + 78 + 55 + 22 + 14)/7
= 43.4.
43.4 is the appropriate measure of central tendency.
(ii)
Ex: Marks scored by a student in 5 subjects.
20,30,55,65,75
Median = 55.
55 is an appropriate measure of central tendency.
Hope this helps!
