Objective
The objective of this individual assessment is to test your ability in conceptualizing and
solving analytics problems, your skills in R programming, and your ability in providing
business recommendations based on analytics results. In this assignment, you will
undertake an exploratory data analysis in the role of a data analyst. You are expected
to analyze data using statistics and visualisation techniques. These learning content
has been covered in the course up until the end of week 3.
Description
A manufacturing company MechTech is launching an initiative of improving its
workforce performance. The leadership team aims to explore the factors that are
associated with the job performance of their employees. MechTech has contracted
you as a data analyst to investigate these factors. The company provides you with the
data including attributes such as employees’ demographic information (e.g., gender,
age, education) and job information (e.g., department, years at the company,
mentoring, training). A detailed description of each attribute of the dataset is presented
in Appendix A: Data Dictionary.
MechTech requires you to:
1. conduct descriptive analytics to identify the factors that are associated with the
job performance of their employees. Note that Descriptive Analytics refers to
statistics and visualization techniques. As an example, a box plot and a bar
chart are considered as two different techniques.
2. provide recommendations to its leadership team about how to improve job
performance based on the descriptive analytics results.
How to Download Dataset
Use the following R-script to directly download the data in R-studio by typing the last
7 digits of your zID (e.g., zID is 3241403) as highlighted in yellow below:
Note that students will have a personalized data set, thereby different results and
recommendations even using the same analytics technique.
Guidance on Data Analysis
1. There is not a single correct answer to the assignment. The dataset includes
many attributes for you to explore, and some attributes are likely to be more
useful than others. Therefore, it is important that you systematically explore
different variables in the dataset to facilitate your analysis.
2. Consider potential, key factors that are associated with low performance across
the workforce by relating them to real-world scenarios. You can look for industry
examples and/or academic references to justify your selection of variables.
3. Although you may create many graphs for your assignment, you only want to
include figures that support your main findings. Those graphs should
summarize the associations that you are reporting.
4. Your recommendations to the leadership team at MechTech should be well
supported by your visualizations and/or statistics summaries.
5. You should explicitly state any key assumptions that impact your data analysis.
Requirements:
1. Problem Identification (10%)
• Formulate a business problem.
• State the purpose of the analytics tasks.
2. Data Analysis (50%)
• Justify the selection of techniques and variables. More than 3 variables
are recommended for your analysis.
• Apply appropriate descriptive analytics techniques to analyze data.
• Use visualization graphs to explore associations between variables.
Visualization graphs include histograms, bar charts, scatter plots, box
plots, etc.
• Interpret analytics results.

3. Recommendations (20%)
• Provide recommendations based on analytics results.
• Support recommendations use state-of-the-art industry practices and/or
academic references.
• Use supplementary readings to this assessment and self-researched
materials to develop recommendations.
4. Communication (10%)
• Demonstrate proficiency in reading and writing in English.
• Uses language, figures, and/or tables to convey qualitative and
quantitative information effectively and accurately.
• Attach the codes of your R programming (not a screenshot) in the
Appendix of your report.
5. Organization and structure of the report (10%)
• Develop a logical structure to organize the sections of your report.
• Use academic referencing in Harvard style. Refer to UNSW guideline:
https://www.student.unsw.edu.au/harvard-referencing
• An example for structuring and developing your report is provided in
Appendix B
Submission Instructions
• A written report with all relevant codes in an appendix.
• A cover sheet with signature.
• Word limit is 750 words with 10% leeway.
Please note:
1) the codes do not count towards the word limit;
2) 10% penalty applies to missing a signed cover sheet in the submission;
3) 5% penalty applied to exceeding the word limit.
Late Submission Penalties
1. Late submission will incur a penalty of 5% per day or part thereof (including
weekends) from the due date and time. An assessment will not be accepted
after 5 days (120 hours) of the original deadline unless special consideration
has been approved. An assignment is considered late if the requested format,
such as hard copy or electronic copy, has not been submitted on time or where
the ‘wrong’ assignment has been submitted.
2. No extensions will be granted except in the case of serious illness,
misadventure, or bereavement, which must be supported with documentary
evidence. Requests for extensions must be made to the Lecturer-in-charge by
email and be accompanied by the appropriate documentation no later than 24
hours before the due date of the assignment. In circumstances where this is not
possible, students must apply for Special Consideration.
3. The Lecturer in Charge is the only person who can approve a request for an
extension. If you do make a request for an extension, the Lecturer in Charge
will email you and the course convener with the decision. Note: A request for
an extension does not guarantee that you will be granted one.
Smarthinking English Support
“… an online writing support platform officially sanctioned by UNSW. Students can
submit drafts of their writing to a Smarthinking tutor or connect to a Smarthinking
tutor in a real-time session and receive comprehensive feedback on a variety of
writing areas”. https://www.student.unsw.edu.au/smarthinking
Smarthinking is available on the COMM1190 Moodle Site.
Using the service, you can:
• Submit your drafts to a Smarthinking tutor for comprehensive feedback on
your writing typically within 24 hours; or
• Connect to a Smarthinking tutor in a live one-on-one session about writing.
• Receive comments on a variety of writing areas including clarity of your
