Answer 1

Given:

The mean and median of a frequency distribution are 72.5 and 73.9 respectively.

To find:

The mode of the frequency distribution.

Solution:

1) We have the relation of mean, mode and median of the frequency distribution.

• Mode = 3Median-2Mean

2) Mean = 72.5

Median = 73.9

• Mode = 3Median-2Mean
• Mode = 3×73.9-2×72.5
• Mode = 221.7-145
• Mode = 76.7

Mode of the frequency distribution is 76.7
