Question
Choose the data technology (Q,H,U, or S) that is most appropriate for each of the following business questions/scenarios. Q – SQL Querying H – Statistical Hypothesis Testing U – Unsupervised Data Mining/Pattern Finding S – Supervised Data Mining a) ___ For my on-line advertising the decision tree model yields a response rate of 0.5% and the old, manual targeting model yields 0.3%. Is the decision tree model really better? b) ___ I want to know which of my customers are the most profitable. c) ___ I need to get data on all my on-line customers who were exposed to the special offer, including their registration data, their past purchases, and whether or not they purchased in the 15 days following the exposure. d)___ I would like to segment my customers into groups based on their demographics and prior purchase activity. I am not focusing on improving a particular task, but would like to generate ideas. e) ___ I have a budget to target 10,000 existing customers with a special offer. I would like to identify those customers most likely to respond to the special offer. f) ___ I want to know what characteristics differentiate my most profitable customers.
Explanation / Answer
Answer :
Q – SQL Querying H – Statistical Hypothesis Testing U – Unsupervised Data Mining/Pattern Finding S – Supervised Data Mining
a) ___ For my on-line advertising the decision tree model yields a response rate of 0.5% and the old, manual targeting model yields 0.3%. Is the decision tree model really better?
Answer : S – Supervised Data Mining
This requires supervised data coordination.
b) ___ I want to know which of my customers are the most profitable.
Answer : H – Statistical Hypothesis Testing
Answer will get only after testing Hypothesis
c) ___ I need to get data on all my on-line customers who were exposed to the special offer, including their registration data, their past purchases, and whether or not they purchased in the 15 days following the exposure.
Answer: Q – SQL Querying
For this Structure Query Language helps to get the systematic data.
d)___ I would like to segment my customers into groups based on their demographics and prior purchase activity. I am not focusing on improving a particular task, but would like to generate ideas.
Answer: U – Unsupervised Data Mining/Pattern Finding
What data that we are looking is completely Unsupervised
e) ___ I have a budget to target 10,000 existing customers with a special offer. I would like to identify those customers most likely to respond to the special offer.
Answer: Q – SQL Querying
