DPBS1110 Evidence-Based Problem Solving
Assessment 2b: Assessment Guide
You have been asked to do further investigation and provide a recommendation to
Australian Airlines Association (AAA). In particular, you have been asked to provide a
recommendation on whether the AAA officials need to interfere to address the flight
cancellation problem. Recommend at least one policy that AAA could consider.
1. Solve lt! 'Statistical Toolbox'
This section of the report is approximately 500 words (guide only, not a word limit).
After your initial investigation and feedback from various stakeholders, it has been
advised that there are other important factors which affect flight cancellations.
To understand whether these factors play an important role, you will need to
(i) formulate a multiple linear regression model and (ii) explain whether the
relationship is statistically and/or economically significant.
The use of a multiple linear regression, confidence intervals and hypothesis testing
would help you address this and thus provide evidence for your arguments.
In addition to interpreting the results of your analysis you will also need to draw to
attention issues of causality and confoundment which can impact the conclusions
from the analysis.
As a part of this assessment, assumptions and limitations need to be explicitly
identified. e.g. What variable would you want to have in an ideal situation? Do you
have this variable in the dataset?
Word limit: A maximum of 1,500 words (no minimum word limit; graphs, figures and
reference list are excluded from the word count). A 10% penalty will apply if you exceed
the word count.
Structure and format: No introduction or executive summary are required. You are
required to write in a business report style (i.e. formal language, etc).
Referencing style: Harvard (see The 'In-Text' or Harvard method for more information).
2. Solve lt! 'Ethics Toolbox'
This section of the report is approximately 500 words (guide only, not a word limit).
Your client, the Australian Airlines Association, is especially concerned with the ethical
issue that could arise. Apply the 7-step ethical decision-making framework from Unit 3 to
answer this question.
Should airline impose mandatory COVID19 vaccination to all their workers?
Make sure your position on the ethical issue (step 7 in the framework) is clearly presented.
3. Solve It! 'Information Toolbox'
This section of the report is approximately 500 words (guide only, not a word limit).
After compiling all of the above evidence, you are now ready to consolidate this and other
evidence that you researched, and provide your recommendations to your Team Leader
for inclusion on the main report.
Your instructions are to:
Write your report with a clear problem-solving and decision-making logic
Tell a compelling story with a clearly articulated report argument structure.
You MUST include either a grouping or argument structure logic tree. (the logic tree
will not be included in the word count)
Ensure that your recommendations are persuasive and include specific course of
actions for the government.
Be consistent with the statistical and ethical analysis conducted in the report.
