The link above will take you to a case study on the relationship between physical strength and job performance done using 147 workers as a sample. You are free to explore the links on this page. Note that the following links exist on the left-hand margin of the webpage:

1.Background

2.Method and Procedure

3.Univariate Statistics

4.Scatterplots

5.Correlations

6.Regression

7.Raw Data

You will see that the webpage is set up for understanding the process of applying statistics in the real world. Here is what you are expected to do as a part of your Final Exam for this class. First, get familiar with the raw data and copy it over to an Excel sheet. Alterntively, use the Excel Sheet that is included with this assignment. Then, write out the case study in your own words using the following sections. You are expected to run the tables, plots, correlations, and regressions using Excel and provide the tables as a part of your write up. You are also required to submit your Excel file along with your Word document that includes these sections. Include citations where relevant.

1.Introduction: Give a short background of the case and describe the potential for a relationship that could exist between the variables being considered. Clearly identify which specific relationship you are interested in (the webpage talks about two relationships, and you can choose which one you would like to pursue for your study).

2.Hypothesis: This section should only be about 1 or 2 sentences long with clear null and alternate hypotheses identified separately.

3.Data Characteristics: Include the following in this section:

a.Summary Statistics - basic statistical table(s) for all variables of interest

b.Scatterplots and Correlations - identify which variables need to be plotted and create a correlation table for variables of interest

4.Regression Analysis and Results: This is where you would present the results of the regression analysis that tests the relationship you're interested in. Discuss the meaning of these results in one or two sentences.

5.Conclusion: Identify what is the result of your study and whether you rejected or failed to reject your null hypothesis in one or two sentences.
