Among the following options, what is the weight (in kg) that appears least number of times in the given data?

1. 52
2. 50
3. 58
4. 54

Answer 1

Correct Answer - Option 2 : 50

Given:

The following are the weights (in kg) of 25 students:
58, 55, 53, 50, 53, 51, 52, 54, 53, 52, 54, 53, 58, 53, 59, 55, 53, 52, 51, 54, 53, 59, 55, 53, 52

Calculation:

Weights of the 25 students in ascending order are as follow:

50, 51, 51, 52, 52, 52, 52, 53, 53, 53, 53, 53, 53, 53, 53, 54, 54, 54, 55, 55, 55, 58, 58, 59, 59

Weight 50 kg has the lowest frequency, 1 in the given set of data values. 

∴ 50 kg appears least number of times in the given data.
