Question

For which data set, the mean is not a good representative measures of central tendency.

Options:

A . There are 7 classes with the below frequencies. {10, 12, 15, 17, 14, 15, 17}

B . There are 6 classes with the below frequencies. {2, 20, 25, 17, 19, 22}

C . There are 7 classes with the below frequencies. {5, 7, 5, 6, 4, 5, 7}

D . There are 6 classes with the below frequencies. {17, 20, 25, 17, 19, 22}

Answer: Option B
:
B
We know that extreme values in the data affect the mean. Here only for the data set{2, 20, 25, 17, 19, 22}, we find the extreme value as one class has the frequency as 2 and the others have frequency 20, 25, 17, 19 and 22.
