Questions:
1. Discuss the 3 major groups of analytic approaches in terms of the kinds of questions answered by their output
2. What operational criteria are commonly used to define the label “Big Data”?
3. difference between descriptive, predictive, and prescriptive analytics?
I expect 3 pages of fact-based material to answer these questions. If you copy any materials from texts or the internet, you MUST provide a citation for them to avoid plagiarism.
