The client needs the preliminary findings by the end of the day. Your boss asks you to first compute some basic statistics and then analyze the results in the four questions given in the Excel spreadsheet.

Background information on the Data

The data set in the spreadsheet consists of 364 records that you will be analyzing from the Bureau of Labor Statistics. The data set contains a listing of several jobs titles with yearly salaries ranging from approximately $30,000 to $200,000 for the state of Minnesota.

What to Submit

Your boss wants you to submit the spreadsheet with the completed calculations, answers, and analysis.
The following questions are include in the attached excel file.

. Provide a brief overview of the scenario you are given and describe the data set.
1b. Describe how you will be analyzing the data set.
1c. List all variables in the data set. Define each variable as follows and explain your reasoning.
i. Provide the two variable names in the data set.

ii. Define both variable as either Quantitative or Qualitative. Explain your answers.

iii. For the quantiative variable listed, define them as either Discrete or Continuous. Explain your answer.
iv. Provide the level of measurement for both variables. Explain your answers.

  1. Name and describe each Measure of Center below. Include the advantages and disadvantages of each Measure of Center.
    4a. Calculate the Measures of Center and Measures of Variation on the "Data" tab in this document.
    Under each measurement, provide the following: the calculation (including the Excel formula), the value, the units of measurement, and an interpretation of the calculation in context of the scenario.

i. Mean

ii. Median

iii. Mode

iv. Midrange

v. Range
