Consider the following set of values:
31, 27, 30, 28, 28, 29, 23
What can you say about the mean, median and mode of these values?


A) They are the same

B) They are different

C) Cannot say surely

D) None of These

Correct Answer:
A) They are the same

Description for Correct answer:
Given data is 31, 27, 30, 28, 28, 29, 30, 31

I. Mode = 28

To find median the data can be written in ascending order.

23, 27,28, 28, 29, 30, 3.1.

II. Median = 28

III. Mean = \( \Large \frac{31+27+30+28+28+29+23}{7}=\frac{196}{7} \) = 28

For the given data, mean, median and mode are the same.
