Answer:

In this scenario, there is a data available from an organization on their annual salary for 200 employees. The measurement of these data using different scales mentioned as given below:

• The nominal scale measures data into categories. Therefore, all 200 employees’ annual salaries can be categorized based on permanent employees & third party contract employees, different divisions or departments wise and also designation wise.

• The ordinal scale provides ranking to the information. Therefore, the data on highest salaried employees to lowest salaried employee can be obtained. Similarly, highest paid diepartment to lowest paid department data can also be obtained for all 200 employees.

• The interval scale can measure the salary range based on designation order. For instance: the salary range for junior trainee is $5,000 - $6,500. For all the 200 employees, salary range can be categorized based on their designation

• Ratio scale is useful to make a comparison of number of times the salaries of senior management employeers is greater to the junior designation employees. For instance: salaries of senior engineers are 2 times greater than junior engineers.
