Math 533

Course Project Part A

AJ Davis Department Store Customer Research
A. Brief Introduction
The department store AJ Davis would like to find out more information about their customers. A sample of 50 credit customers is selected with data collected on the following five variables: 1. LOCATION (Rural, Urban, Suburban)

2. INCOME (in $1,000's – be careful with this)
3. SIZE (Household Size, meaning number of people living in the household) 4. YEARS (the number of years that the customer has lived in the current location) 5. CREDIT BALANCE (the customers current credit card balance on the store's credit card, in $). This report presents the findings of three individual variables extensively which include location, income, and credit balance. We will also discuss three pairing of variables extensively which include: location and income, income and credit balance, as well as location and credit balance. These variables and pairings will give AJ Davis the most information about their customers. B. 1st Individual Variable is location:

Location is very important to AJ Davis because knowing where your customers come from is the basis for most of your research. From location you can draw a correlation with every variable.

Interpretation: From the pie chart we can conclude that most of the customers come from an urban location about 44%. The rural and suburban areas are roughly the same with the least being from a rural area. 30% of the stores customers are from a suburban area and 26% are from a rural area.

C. 2nd Individual Variable is Income:
Knowing the income of customers gives us an idea of what socio-economic group is shopping at the AJ Davis department store.

Descriptive Statistics: Income ($1000)
