Correct Answer - Option 3 : 53
Given:
Observations are 32, 45, 16, 28, 69, 34, 29, 54, 48
Concept used:
The difference between the upper limit and the lower limit of a class is called its Range or class size
Range = Upper limit - Lower limit
Calculation:
According to the question
Arranging data in ascending order = 16, 28, 29, 32, 34, 45, 48, 54, 69
Here, Upper limit = 69, Lower limit = 16
Range = Upper limit - Lower limit
⇒ 69 - 16
⇒ 53
∴ The range of given data is 53.
