Q5Which measure of central tendency is most appropriate for the data listed?
72, 55, 67, 89, 120, 76

A. mean
B. median
C. mode

Q6John has taken an aptitude test 6 times and his scores are 82, 85, 90, 95, 27 and 87. Which measure of central tendency is most appropriate for his scores?
A. Median
B. Range
C. Mode
D. Mean

Step: 1
Range is the difference between the maximum and minimum values of the data set.
Step: 2
Mode is used to find the occurrence of maximum times of a data value.
Step: 3
Mean is a better measure of central tendency if there is no outlier in the data.
Step: 4
27 is the outlier in the data as it is far apart from other values. So, it may skew the central tendency.
Step: 5
As the outlier influences the mean, the median is the better measure of the central tendency.
Q7Which measure of central tendency is most appropriate for the data listed?
27, 28, 30, 32, 29, 34, 31, 33, 35

Mean is a better measure of central tendency if there is no outlier in the data.
Step: 2
There is no outlier in the given data.
Step: 3
So, mean is the most appropriate measure of central tendency for the given data.

Step: 3
So, the measure of central tendency that is the best for the given situation is Mode.
Q10The scores of students of four teams A, B, C, and D in their math tests were recorded. Each team reported an average of 90. Which of the following measure of central tendency was used by the teams?
A: 85, 81, 91, 96, 97
B: 93, 92, 90, 90, 91
C: 85, 81, 94, 93, 90
D: 85, 89, 90, 90, 90

A. Team C used median
B. Team A used mode
C. Team D used mean
D. Team B used median

Step: 1
Mode does not exist for Team A.
Step: 2
90, 90, 91, 92, 93
[Ordered list of Team B.]
Step: 3
Median of Team B is 91.
[Middle score in the ordered list.]
Step: 4
81, 85, 90, 93, 94
[Ordered list of Team C.]
Step: 5
Median of Team C is 90.
[Middle score in the ordered list.]
Step: 6
Mean of Team D = 85 + 89 + 90 + 90 + 905 = 88.8
Step: 7
Average 90 is obtained by taking median for team C scores.
Step: 8
So among the choices, Team C used median is true.
Correct Answer is :   Team C used median
