Correlation Between Incident Cost and Day Lost

Washington University of Virginia – Fall 2021

Big Data Analytics

Final Exam

Overview

For this assignment, you will come up with a research question and explore it using the techniques of data analysis that we have described in class and explored in the labs.

You will develop your own research question and answer that using data from the attached work safety data.

You will perform all of the data processing and analysis steps performed using excel or any other software of your choice.

Steps you will complete include:

• Open the attached work safety dataset.
• Combine and clean data, recode and prepare excel spreadsheets with the variables of interest
• Change variable names and labels
• Check for missing data types and variables
• Code categorical variables in letters or symbols (age group, gender, incident cost, shift) into numerical variables.
• Compute descriptive statistics (mean, standard deviation, median, minimum, maximum) for incident cost and day lost.
• Compute frequencies for age group, gender, incident type and shift.
• Perform histograms of incident cost and day lost.
• Perform bar graphs and pie chart of age group, gender, incident type and shift.
• Perform a scatterplot of incident cost (dependent variables) versus day lost (independent variable).
• Compute a correlation between incident cost and day lost.
• Perform a simple linear regression analysis between incident cost and day lost.
• Perform a multiple linear regression between incident cost and day lost, age group, gender, incident type and shift.
• Interpret the analyses
• Write-up your findings

Components of your analysis

Your analysis must include the following and you must interpret the findings. Statistics that exist on their own with no interpretation will not count.

1. Descriptive statistics:

1.1 Show output for and describe descriptive statistics for at least 4 variables

1.2 Show and describe histograms and scatterplots (total of 7 graphics). Histograms with “frequency” on the y-axis are often the most straightforward to interpret.

3. Correlation:

Show output for and describe correlations for at the two continuous variables.

4. Regression:

4.1. Complete the bivariate regressions, show output for and describe (coefficients, t-stat, p-value, r-squared)

4.2. Complete the multiple linear regression, show output for and describe (coefficients, t-stat, p-value, r-squared)

Note: We do not want to read about all of the intermediary steps that you did, see all of the output you created, hear about syntax errors, things you fixed, etc. Do not include all of your work – only the relevant parts.

Requirements:

Your assignment includes the following:

1. A narrative of the analysis you conducted, complete with an introduction, Stata output inserted in the body of the text, your interpretations of the output, and a conclusion.

Be sure to:

• Explain your reasoning for including each independent variable, along with your hypothesis for how you thought it would affect the dependent variable (again, you could help to illustrate your reasoning using scatter plots, histograms, or descriptive statistics)
• Be sure to explain any regression outputs you include clearly, interpreting the r-squared, the coefficients on the independent variables, and the related p-values in plain language.
• What can you conclude based on your results? Provide a clear conclusion

 

RUBRIC QUALITY OF RESPONSE NO RESPONSE POOR / UNSATISFACTORY SATISFACTORY GOOD EXCELLENT Content (worth a maximum of 50% of the total points) Zero points:  Student failed to submit the final paper. 20 points out of 50:  The essay illustrates poor understanding of the relevant material by failing to address or incorrectly addressing the relevant content; failing to identify or inaccurately explaining/defining key concepts/ideas; ignoring or incorrectly explaining key points/claims and the reasoning behind them; and/or incorrectly or inappropriately using terminology; and elements of the response are lacking. 30 points out of 50:  The essay illustrates a rudimentary understanding of the relevant material by mentioning but not full explaining the relevant content; identifying some of the key concepts/ideas though failing to fully or accurately explain many of them; using terminology, though sometimes inaccurately or inappropriately; and/or incorporating some key claims/points but failing to explain the reasoning behind them or doing so inaccurately.  Elements of the required response may also be lacking. 40 points out of 50:  The essay illustrates solid understanding of the relevant material by correctly addressing most of the relevant content; identifying and explaining most of the key concepts/ideas; using correct terminology; explaining the reasoning behind most of the key points/claims; and/or where necessary or useful, substantiating some points with accurate examples.  The answer is complete. 50 points:  The essay illustrates exemplary understanding of the relevant material by thoroughly and correctly addressing the relevant content; identifying and explaining all of the key concepts/ideas; using correct terminology explaining the reasoning behind key points/claims and substantiating, as necessary/useful, points with several accurate and illuminating examples.  No aspects of the required answer are missing. Use of Sources (worth a maximum of 20% of the total points). Zero points:  Student failed to include citations and/or references. Or the student failed to submit a final paper. 5 out 20 points:  Sources are seldom cited to support statements and/or format of citations are not recognizable as APA 6th Edition format.

There are significant errors of the formation in the references and citations. And/or there is a significant use of highly questionable sources. 15 out 20 points:  Credible Scholarly sources are used effectively support claims and are, for the most part, clear and fairly represented.  APA 6th Edition is used with only a few minor errors.  There are minor errors in reference and/or citations. And/or there is some use of questionable sources. 20 points:  Credible scholarly sources are used to give compelling evidence to support claims and are clearly and fairly represented.  APA 6th Edition format is used accurately and consistently. The student uses above the maximum required references in the development of the assignment. Grammar (worth maximum of 20% of total points) Zero points:  Student failed to submit the final paper. 5 points out of 20:  The paper does not communicate ideas/points clearly due to inappropriate use of terminology and vague language; thoughts and sentences are disjointed or incomprehensible; organization lacking; and/or numerous grammatical, spelling/punctuation errors  10 points out 20:  The paper is often unclear and difficult to follow due to some inappropriate terminology and/or vague language; ideas may be fragmented, wandering and/or repetitive; poor organization; and/or some grammatical, spelling, punctuation errors 15 points out of 20:  The paper is mostly clear as a result of appropriate use of terminology and minimal vagueness; no tangents and no repetition; fairly good organization; almost perfect grammar, spelling, punctuation, and word usage. 20 points:  The paper is clear, concise, and a pleasure to read as a result of appropriate and precise use of terminology; total coherence of thoughts and presentation and logical organization; and the essay is error free.
