Question

Please tell me the answer to the question

Answer 1

(i) When the data does not change much, mean is an appropriate measure of a central tendency.
FOR EXAMPLE :-
---------------------------
Marks of a student in 5 tests
7,6,6,7,5
=> mean = [(7+6+6+7+5)/5]
= 31/5
= 6.2
Here 6.2 is an appropriate measure of a central tendency.
(ii) When the data has a very high or low value then mean is not an appropriate measure of a central tendency.

Then median can be an appropriate measure.
FOR EXAMPLE :-
--------------------------
Runs scored by Shikhar Dhawan in 5 matches
20,25,100,21,23
Mean = [(20+25+100+21+23)/5]
= 189/5
= 37.8
But median
Arrange the data in the ascending order
20,21,23,25,100
Middle term = [(5+1)/2] th term
= 3th term
Here 3rd term is 23
Hence median = 23 is an appropriate measure of a central tendency
