Problem Set Week One All statistical calculations will use Employee Salary Data Set

1. Using the Excel Analysis ToolPak function descriptive statistics, generate and show the descriptive statistics for each appropriate variable in the sample data set.

1. For which variables in the data set does this function not work correctly for? Why?

2. Sort the data by Gen or Gen 1 (into males and females) and find the mean and standard deviation for each gender for the following variables:

1. sal, compa, age, sr and raise. Use either the descriptive stats function or the Fx functions (average and stdev).

3. What is the probability for a:

1. Randomly selected person being a male in grade E?

2. Randomly selected male being in grade E?

3. Why are the results different?

4. Find:

1. The z score for each male salary, based on only the male salaries.

2. The z score for each female salary, based on only the female salaries.

3. The z score for each female compa, based on only the female compa values.

4. The z score for each male compa, based on only the male compa values.

5. What do the distributions and spread suggest about male and female salaries?

6. Why might we want to use compa to measure salaries between males and females?

5. Based on this sample, what conclusions can you make about the issue of male and female pay equality?

6. Are all of the results consistent with your conclusion? If not, why not?

ID	Sal	Compa	Mid	Age	EES	SER	G	Raise	Deg	Gen1	Gr
1	58	1.017	57	34	85	8	0	5.7	0	M	E	The ongoing question that the weekly assignments will focus on is: Are males and females paid the same for equal work (under the Equal Pay Act)?
2	27	0.870	31	52	80	7	0	3.9	0	M	B	Note: to simplfy the analysis, we will assume that jobs within each grade comprise equal work.

4	66	1.157	57	42	100	16	0	5.5	1	M	E	The column labels in the table mean:
5	47	0.979	48	36	90	16	0	5.7	1	M	D	ID – Employee sample number	Sal – Salary in thousands
6	76	1.134	67	36	70	12	0	4.5	1	M	F	Age – Age in years	EES – Appraisal rating (Employee evaluation score)
7	41	1.025	40	32	100	8	1	5.7	1	F	C	SER – Years of service	G – Gender (0 = male, 1 = female)
8	23	1.000	23	32	90	9	1	5.8	1	F	A	Mid – salary grade midpoint	Raise – percent of last raise
9	77	1.149	67	49	100	10	0	4	1	M	F	Grade – job/pay grade	Deg (0= BS\BA 1 = MS)
10	22	0.956	23	30	80	7	1	4.7	1	F	A	Gen1 (Male or Female)	Compa - salary divided by midpoint, a measure of salary that removes the impact of grade

12	60	1.052	57	52	95	22	0	4.5	0	M	E	This data should be treated as a sample of employees taken from a company that has about 1,000
