    Dealing with the following scenario: American Intellectual Union (AIU) has assembled a team of researchers in the United States and around the world to study job satisfaction. Congratulations, you have been selected to participate in this massive global undertaking.
    The study will require that you examine data, analyze the results, and share the results with groups of other researchers. Job satisfaction is important to companies large and small, and understanding it provides managers with insights into human behavior that can be used to strengthen the company's bottom line.

    The data set for the study is a sample of a survey conducted on the population of the American Intellectual Union (AIU). It is available via the following link: Excel 2007 DataSet with DataSet Key which contains the following nine sections of data that will be used throughout our course:

    Gender
    Age
    Department
    Position
    Tenure
    Overall Job Satisfaction
    Intrinsic Job Satisfactionâ?"Satisfaction with the actual performance of the job
    Extrinsic Job Satisfactionâ?"external to the job, for example, office location, your work colleagues, your own office (cubicle/hard walled office, etc),
    Benefitsâ?"Health insurance, pension plan, vacation, sick days, etc.

    Complete the following:

    Examine two of the nine sections of data:
    -one section of qualitative data (choose either Gender or Position)
    -one section of quantitative data (choose either Intrinsic or Extrinsic)
    -Each section should include all data points listed in the column for the variable. The requirements include:
    1.) Identify the data you selected.
    2.) Explain why the data was selected.
    3.) Explain what was learned by examining these sets of data.
    4.) Your analysis should include using Microsoft Excel to obtain information about the data through the use of three measures of central tendency (mean, median, mode).
    5.) Your analysis should also include the use of two measures of variability (standard deviation and variance). Some measures are appropriate for qualitative data, and some are appropriate for quantitative data.
    6.) If a measure is not applicable, then explain why.
    7.) You will have to also provide one chart/graph for each of the results of the two processed sections of data (2 total), such as a pie or bar chart or a histogram. (A table is not a chart/graph.) Ensure that you label the chart/graph clearly.
    8.) Can you discuss what you additionally learned from the results of this process.
    9.) Than explain to me why charts/graphs are important in conveying information in a visual format and why standard deviation and variation are important.
    You will need to combine all of the items above into one comprehensive report. Please see attachment.

    Solution Summary

    Your tutorial is 515 words and includes three charts and 2 references. The raw analysis is in Excel for you (scroll down to the bottom of the data points for analysis). The discussion explains the importance of the measures of central tendency (one at a time) and the measures of dispersion. Then, it gives an example of how charts help in a way that statistics cannot.
