Download Solution PDFThe correct answer is that it remains same.
Key Points
The formulae we need for solving the problem are as follows:
Here, since all the observations are doubled the value for Quartiles becomes:
This is the same value as the coefficient of quartile deviation when the values of the observation of the data set were unchanged.
Thus the correct answer is- If each observation in a data set for the number of employees in different divisions is doubled then the coefficient of quartile deviation remains same.
Additional Information
- The formula in this case used is for grouped data as the question specifically says observation of different employees for different departments.
- The same result can be derived for ungrouped data as well.
