• Self-management skills.
Assessment Overview:
This assessment is designed to develop students’ skills in the co
ect usage of analytical techniques and interpreting data for making managerial decisions. The main task is to analyse business data and to prepare a report for management based on an analysis of the data.

    Assignment-3 tasks and description Tasks
    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 e
or 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.
    Use Word
    Combine item 3 and 4 and submit it on Turnitin
Self-reflection on feedback from assignment-2
    Reflection Proforma:
Use the reflection proforma included in this document to complete your self-reflection and attach it at the end of your report (item-3 above)
    Use Word
# use Excel clean dataset and Data Dictionary from Assignment-2
**Refer to LEO on instructions on how to submit files on ePortfolio (Same process as assignment -2)
Refer to case study (page-6) – the same case study as before.

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)
Important notes for assignment 3
·     1000 word report writing
· Case scenario – same data set, data cleaning and data pre processing
· Individualisation – dashboard (multiple charts, either Excel or Tableau)
· Data classification tool – Knime software (understand from week 9 materials) free download
· Study Weeks 7-9 materials
· Reflection – last page of the assessment 3 specifications and must be included in the report
· Analyse the case study once again and find out multiple problems and problem causes
· How to submit – upload Excel or Tableau,Knime file, paste secret link into Word doc and upload into LEO. Same procedures from assignment 2
· Dashboard
· Contain relevant charts from Week 7
· Spreadsheet – data cleaning / pre processing
· Each image should have a caption
· Report – appropriate format
· Data analytical tools – Excel or Tableau
· Reflect from the beginning before questions
· Classification tool – experiment decision tree and e
or rate should be less than 15%.
· To calculate the kick rate for each chosen input, only use and show the decision tree in the Knime software.
· To calculate kick rate for auction field = Total no of kicks / Total no of cars (for each auction site)
· In report writing, must explain interpretation of Tableau/Excel sheet dashboard, how they a
ive at the input data file and interpretation of the outcome of the decision tree.
· Dashboard – must provide reasonable and sensible charts (multiple charts), that chart should show Kicks rate
· Knime decision tree – must have a working workflow with co
ect class column, class column of the tree learner should be is ‘bad buy’. Needs to be less than 15% (if 15-20% the marker will still accept it)
· Report writing – always write in 3rd person, avoid ‘I’, ‘we’, ‘she’ words etc. Provide good reasons of your choices in relation to data analysis (Wk 7) and data mining (Wk 7)
· Describe how data analysis you did and explain why?
· Must conclusion the report as a data analyst
· In Knime, you must check the confusion matrix in the scorer and try to improve the e
or rate
· Charts should help the decision marker with solving the problem
Report should contain: - in report, do introduction, theory component of the classification tool you've used, the analysis/interpretation of the classification tool and conclusion

Data visualisation
• “The use of visual representations to explore, make sense of,
and communicate data.”
Data visualization vs. Information visualization
• Information = aggregation, summarization, and
contextualization of data
• Related to information graphics, scientific visualization, and
statistical graphics
• Often includes charts, graphs, illustrations, …

ief history
• Data visualization can date back to the second century AD
• Most developments have occu
ed in the last two and a half
• Until recently it was not recognized as a discipline
• Today’s most popular visual forms date back a few centuries
