Question 1
Shop A only sells three products, namely, product X, product Y and product Z to the customers. Last week, 4000 customers shopped in Shop A, and each customer purchased at least one product. Customers are divided into 4 demographic segments which are displayed in table 1:
Customer Segment ID Gender Marital Status Number of Customers
1 Male Single 1000
2 Male Married 1000
3 Female Single 1000
4 Female Married 1000
The purchase patterns in each segment is displayed in Table 2, Table 3, Table 4 and Table 5 respectively:
Table 2: Purchase patterns of Customers in Segment 1(Male and Single)
Choose X =100
Choose Y =200
Choose Z =100
Choose X and Y =100
Choose Y and Z =50
Choose X and Z=50
Choose X,Y,Z =400
(Interpretation: In Pattern 1,100 male and single customers purchased product A only. Similarly, in pattern 7,400 male and single customers purchased all products)
Table 3: Purchase patterns of Customers in Segment 2(Male and Married)
Choose X =100
Choose Y =200
Choose Z =100
Choose X and Y =400
Choose Y and Z =50
Choose X and Z=50
Choose X,Y,Z =100
Table 4: Purchase patterns of Customers in Segment 3(Female and Single)
Choose X =100
Choose Y =200
Choose Z =100
Choose X and Y =50
Choose Y and Z =50
Choose X and Z=400
Choose X,Y,Z =100
Table 5: Purchase patterns of Customers in Segment 4(Female and Married)
Choose X =100
Choose Y =200
Choose Z =100
Choose X and Y =50
Choose Y and Z =400
Choose X and Z=50
Choose X,Y,Z =100
Consider four targeting rules below for selling product Z to customers:
Rule 1: IF X THEN Z.
Rule 2: IF Female and X and Y THEN Z.
just consider the female tables
Rule 3: IF Married and (X or Y) THEN Z.
just consider the married tables
Rule 4: IF Male and Single THEN Z.
just consider the male and single table
Question A:
Compute the confidence, the support and the lift of all the rules above and summarize the results in table 6 on page 7. You can show me the calculation steps.
Question B
Which one of these four rules is the best targeting rule you recommend? Please justify your answer
