Range of the data = 13
Solution:
To find the range of the given data:
Let us first define what is range.
Range:
The range of the data set is the difference between the highest value and lowest value of the data set.
i. e. Range = Highest value – Lowest value

Range of the data = 115 – 102
= 13
Range of the data = 13
Hence the range of the given data is 13.
