Range of Data
Range of Data:
The range tells us how widely the numbers are spread. In other words, range is the difference of the highest and the lowest observation. To calculate the range of the data we will find the maximum and the minimum value in the data, and the difference between the two is the range for the data.
Illustration 1: The weights (in kg) of 10 students of a class are
43.5, 49.5, 52, 43, 47,44.5, 38.5, 40, 47, 38
Calculate the range of the weights of the students.
Solution: Arranging the data in ascending order,
i.e., 38, 38.5, 40, 43, 43.5, 44.5, 47, 47, 49.5, 52
The greatest weight is 52 kg
And the lowest weight is 38 kg.
Therefore, the range of ( 52 - 38 ) kg = 14 kg
Which of the following statement is true regarding range of data: 1. It tells us how widely the numbers are spread. 2. It is the difference of the highest and the lowest observation. 3. It is the average number of observations. | |||
