To accomplish allocated tasks, you need to examine and analyse the dataset (supermart.xlsx) thoroughly.
Below are some guidelines to follow:
Task 1 – Summarising Dependent Variables
The purpose of this task is to analyse and explore key features of these variables individually. At the
very least, you should thoroughly investigate relevant summary measures/charts and graphs of
these variables. Proper visualisations should be used to illustrate key features.
Your technical report should describe ALL key aspects of each variable.
Task 2. – Model building (predicting Sales)
You should follow an appropriate model building process. All steps (including pre and post model
diagnostics) of the model building process should be included in your analysis. You can have as
many Excel worksheets (tabs) as you require to demonstrate different iterations of your regression
model (i.e., 2.2.a., 2.2.b., 2.2.c. etc.). You must make reasonable/realistic/practical assumptions
about the parameters you are working with in Task 2.
Your technical report should clearly explain why the model might have undergone several
iterations. Also, you must provide a detailed interpretation of ALL elements of the final
model/regression output.
Task 3. – Interaction effect
To accomplish this task, you need to develop a regression model using ONLY the factors discussed
in the meeting (Task 3). In other words, this section of analysis is separate from the regression
model constructed in Task 2. You must make reasonable/realistic/practical assumptions about the
parameters you are working with in Task 3.
Your technical report should clearly explain the role of each variable included in the model. A
proper visualisation technique should be used. Make sure you interpret all relevant outputs in detail
and provide managerial recommendations based on the results of your analysis.
Task 4 – Model building (likelihood of a store opening on Sunday)
You should follow an appropriate model building process. All steps (including pre and post model
diagnostics) of the model building process should be included in your analysis. You can have as
many Excel worksheets (tabs) as you require to demonstrate different iterations of your regression
model. You must make reasonable/realistic/practical assumptions about the parameters you are
working with in Task 4.
You are required to discuss all details of your predictive model/logistics regression output.

Task 5.1 – Model building (likelihood of a store opening an online sales channel)
You should start building the predictive model by including ONLY the variables listed in the ‘minutes
of the meeting – Task 5.1’. You must make reasonable/realistic/practical assumptions about the
parameters mentioned in Task 5.
You are required to discuss all details of your predictive model.
Task 5.2. – Visualising and interpreting predicted probabilities
Your technical report must include the predicted probability visualisation and be supplemented by
practical recommendations to Superstore’s Management.
