Case Study 3 - Fraud Examination Book

Import the ch06_charges.tsv and ch06_approved_vendors.tsv data sets into your analysis software. These files give a list of purchases and vendors that are approved for use, respectively.

Questions:

1. Briefly describe the case.

2. Explain what detection methods or techniques are used to investigate fraud in the case.

3. Were any vendors unused by the purchasing department? What does this fact tell us about these vendors?

If the tutor can bring me an email, I can send the excel. The book doesn't bring anything more, this is all the information in the book about the case.
