Apply Quantitative Reasoning
Now that you have completed your analysis, think about the patterns you have seen in the workforce.
In this final section, you will answer five questions and write a short essay.
1. From the created histogram, it appears that a large share of employees have a salary between $71,000–$90,000 and another small peak at $160,000. This may indicate a reasonable promotion rate for employees. Is this distribution unimodal or bimodal? Please explain.
2. The line chart, as detailed in your “Graph Charts” Excel spreadsheet, shows sales generally increasing over the years, although sales in the first three years were notably slower. Assuming that the sales are linear, please use the Forecast tool to find projected sales for 2020 thru 2024. Hint: An easy way to do this is to highlight the sales from the data page and apply the Forecast tool to this data or use the forecast function in excel. You will generate a chart on a new sheet (tab) with projected sales; rename this sheet “Projected Sales”.
3. The standard deviation provides insight into the distribution of values around the mean. If the standard deviation is small, in general, the more narrow the range between the lowest and highest value. That is, values will cluster close to the mean. From your descriiptive statistics, describe the standard deviations of Salary, Hrly Rate, Yrs Worked, Education, and Age. What does this tell you about the variables?
4. The company has a keen interest in the educational, race, and gender makeup of its workforce. Its emphasis is on a diverse, dynamic workforce. From your “Graph Charts” spreadsheet, describe your pie chart findings for these characteristics of the workforce. Describe how you would determine if the company was meeting expectations on these characteristics.
5. The company is conducting an analysis on how many positions to create to keep up with demand. Specifically, it wants to know an estimate of the number of positions per job title. From your Excel chart, identify the mode of the job title distribution. Describe your findings.
FINAL ESSAY:
Now that you have done all the work with data, you will write a short three- to four-paragraph summary of your analysis. This is important. While you have done a wonderful job with your analysis, you can never assume that the end user will be able to interpret the data the way it should be understood. A supporting narrative is helpful. Never simply provide a “raw data” dump. Instead, seek to provide information!
Structure your essay like this:
Write a one-paragraph narrative summary of your findings, describing patterns of interest.
Provide an explanation of the potential relevance of such patterns.
Provide a descriiption of how you would investigate further to determine if your results are “good or bad” for the company.
Prepare your response in this workbook. (Simply expand this text box to accommodate your essay and other answers.)
