Solved Examples on Range
Example 1: You are given a dataset of the ages of students in a classroom:
18, 19, 20, 21, 22, 35, 18, 23
Solution:
Maximum Value = 35
Minimum Value = 18
Range = 35 – 18 = 17
The range of ages among the students is 17 years.
Example 2: Consider a dataset of exam scores for a class:
Scores: 85, 92, 78, 96, 64, 89, 75, find the range?
Solution:
Maximum Value = 96
Minimum Value = 64
Range = 96 – 64 = 32
So, the range of the exam scores is 32.
Example 3: Imagine a dataset of monthly rainfall (in millimeters) for a city for the past year:
Rainfall: 50, 48, 52, 58, 45, 70, 65, 80, 40, 42, 75, 90, find the range of monthly rainfall for the city?
Solution:
Maximum Value = 90
Minimum Value = 40
Range = 90 – 40 = 50
The range of monthly rainfall for the city is 50 mm
Range in Statistics
In statistics, a range refers to the difference between the highest and lowest values in a dataset. It provides a simple measure of the spread or dispersion of the data. Calculating the range involves subtracting the minimum value from the maximum value.
Range is a fundamental statistical concept that helps us understand the spread or variability of data within a dataset. Range in Statistics provides valuable insights into the extent of variation among the values in a dataset. Range quantifies the difference between the highest and lowest values in the dataset.
Let’s discuss in detail about range in statistics with definition, formula.
