Week 1
    Week 1: Descriptive Statistics, including Probability                                                                            Gender1    Salary
    While the lectures will examine our equal pay question from the compa-ratio viewpoint, our weekly assignments will focus on                                                                            F    36.2
    examining the issue using the salary measure.                                                                            F    42.1
                                                                                F    22.8
    The purpose of this assignmnent is two fold:                                                                            F    23
    1. Demonstrate mastery with Excel tools.                                                                            F    21.8
    2. Develop descriptive statistics to help examine the question.                                                                            F    40.5
    3. Interpret descriptive outcomes                                                                            F    23.6
                                                                                F    23.4
    The first issue in examining salary data to determine if we - as a company - are paying males and females equally for doing equal work is to develop some                                                                            F    67.5
    descriptive statistics to give us something to make a preliminary decision on whether we have an issue or not.                                                                            F    34.1
                                                                                F    35.2
    1    Descriptive Statistics: Develop basic descriptive statistics for Salary                                                                        F    51.1
        The first step in analyzing data sets is to find some summary descriptive statistics for key variables.                                                                         F    25.3
        Suggestion: Copy the gender1 and salary columns from the Data tab to columns T and U at the right.                                                                        F    51
        Then use Data Sort (by gender1) to get all the male and female salary values grouped together.                                                                        F    24.4
                                                                                F    77.2
        a.     Use the Descriptive Statistics function in the Data Analysis tab                                                                     F    22.7
            to develop the descriptive statistics summary for the overall                                 Salary                                    F    23.9
            group's overall salary. (Place K19 in output range.)                                                                    F    22.8
            Highlight the mean, sample standard deviation, and range.                                Mean    44.454                                F    22.6
                                            Standard E
or    2.7040728314                                F    33.5

                                            Standard Deviation    19.1206823591                                F    48.9
        b.    Using Fx (or formula) functions find the following (be sure to show the formula                                 Sample Variance    365.6004938776                                F    65.6
            and not just the value in each cell) asked for salary statistics for each gender:                                Kurtosis    -1.2688729185                                M    57.7
