To calculate: The range and the IQR of the salaries for employees in a department of a company.
The range of the data is
Given information: The data of the salaries for employees in a department of a company in thousand dollars is:
Formula used: The difference between the maximum and minimum values of a data set is known as range.
The difference between the first and third quartiles of the data is the interquartile range (IQR).
Here,
Calculation:
Arrange the list of numbers is ascending order.
The maximum value of the data is
Calculate the range of the given data.
The range in dollars is
The median of the lower half of the data is
Calculate the IQR of the given data.
Thus, the range of the data is
