Pa rt 1: Data Analysis
In the assignment 3 folder on BREO you find an Excel file called “salaries.xls”. Use this file and the

salaries (in thousands of pounds). For each employee you also find data for how many years the
employee is employed by the company and for how many years, the employee is a senior officer in
the company.
It is recommended that you use Excel for all calculations. For your submission, you need to provide
this Excel table in your word document as an appendix. The table should contain a_H calculations. If
you do not provide the Excel table you will fail Part 1 of this assignment. The total of marks in part 1
is 50 marks.
1) Calculate the mean, median, standard deviation of “Salaries”, “Years in the Company” and
Years as a Senior Officer”. (5 Marks)

classes: £0-£50,000; £50,001-£100,000; £100,001-£150,000; £150,001-£200,000; £200,001-

served in the company and how many years an employee served as a senior officer.

5) Test the hypotheses that the “Salaries” depend upon “Years in the Company” or “Years as a
Senior Officer”. In order to do so ran a simple OLS regression of the kind Y = a + ,81X1
82X2 where Y are “Salaries”, X1 are the “Years in the Company” and X2 are the “Years served
