PART A:
EXPLORATORY DATA
ANALYSIS REPORT
INTRODUCTION
AJ DAVIS, a department store chain, has many credit customers and would like to find out more information about their customers (populations of interest). A sample of 50 credit customers were selected with data collected on the following five variables:
1. LOCATION (Rural, Urban, Suburban)
2. INCOME (in $1,000’s)
3. SIZE (Household size)
4. YEARS (number of years the customer has lived at their current address)
5. CREDIT BALANCE (current credit card balance in $)
Tables, graphs, and numerical summary tools will be used to investigate the characteristics and identify data patterns in greater detail. Table 1 contains the data set from a sample of 50 credit customers that will be analyzed within this report. This represents a good sample of the total of all AJ DAVIS credit card customers. The inference of interest is the generalization of credit customer’s credit balances of the 50 sampled customers to the population of all credit customers. The credit balance of the customers in the sample can be used to estimate the percentage all credit customers.
