What is Range?
In a given data set the difference between the largest value and the smallest value of the data set is called the range of data set. For example, if height(in cm) of 10 students in a class are given in ascending order, 160, 161, 167, 169, 170, 172, 174, 175, 177, and 181 respectively. Then range of data set is (181 – 160) = 21 cm.
Range of Data
Range is the difference between the highest value and the lowest value. It is a way to understand how the numbers are spread in a data set. The range of any data set is easily calculated by using the formula given in the image below:
Range Formula
The formula to find the Range is:
Range = Highest value – Lowest Value
Example: Find the range of the given data set 12, 19, 6, 2, 15, 4.
Solution:
Given set is {12, 19, 6, 2, 15, 4}
Here,
Lowest Value = 2
Highest Value = 19
Range = 19 − 2 = 17
Mean, Median and Mode
Mean, Median, and Mode are measures of the central tendency. These values are used to define the various parameters of the given data set. The measure of central tendency (Mean, Median, and Mode) gives useful insights about the data studied, these are used to study any type of data such as the average salary of employees in an organization, the median age of any class, the number of people who plays cricket in a sports club, etc.
Let’s learn more about the Mean, Median, and Mode Formulas, Examples, and FAQs in this article.
