The main task is to analyse business data and to prepare a report for management based on an analysis of the data. The focus is on understanding the use of data analytical tools in a business context and develop written communication skills.
Assignment-3 tasks and description
Tasks Steps/Description Which tools to use to complete? How to Submit your Work
Construct classification tool Construct classification tool to effectively assist the buyer in identification of cars likely to be Kicks.
• Experiment different configurations of the decision tree tool in Knime to find the best one you can. (NB. The error rate should be less than 15%).
• It is expected that while exploring this tool, you may need to keep coming back to explore the dataset to find the best set of inputs for your classification problem#. Use Knime software Data file (Excel), Knime file (of your decision tree) on ePortfolio**
Create Dashboard Create dashboard
• When you are happy with your classification tool, create a dashboard in Tableau or Excel to present these inputs and how they affect IsBadBuy (Kicks).
• Be mindful to choose appropriate visuals for your dashboard. Use Tableau or Excel Dashboard
(Tableau or Excel) on
ePortfolio**
Write a 1000-word report What to include in report?
Once successfully creating a classification tool, describe the tool’s functionality with respect to input contributions to the Kick classification.
• Evaluate your classification tool and explain how it may assist the buyer to reduce the Kicks rate.
• Using the data analytic methods you have learnt in the whole semester, explain your analysis, interpretation in the experiment to support decision makers.

Case Study: Don’t Get Kicked (Same as assignment-2)
One of the biggest challenges of an auto dealership purchasing a used car at an auto auction is the risk that the vehicle might have serious issues that prevent it from being sold to customers. The auto community calls these unfortunate purchases -kicks-.
Kicked cars often result when there are tampered odometers, mechanical issues the dealer is not able to address, issues with getting the vehicle title from the seller, or some other unforeseen problem. Kicked cars can be very costly to dealers after transportation cost, throw-away repair work, and market losses in reselling the vehicle.
Data analysts who can figure out which cars have a higher risk of being kick can provide real value to dealerships trying to provide the best inventory selection possible to their customers.
The challenge of this case study is to predict if a car purchased at an Auction is a Kick (bad buy).
The data dictionary, Carvana_Data_Dictionary.txt, and the data files can be downloaded from LEO under Assessment tab. The data dictionary describes the 34 attributes: RefId, in the first column, contains the ID number for each record. IsBadBuy, in the second column, is the binary dependent variable, where a 1 (one) means “is Kick” and 0 (zero) “is not Kick”. The remaining columns (3 through 30) are independent variables. The dataset contains records for 72,561 vehicles, of which 12.3% are Kick. (Adapted from Kaggle competition)
