Question
MATH 533 Project – Part A

The following outline describes required step by step analysis of the AJ Davis data set.

AJ DAVIS is a department store chain, which has many credit customers and wants to find out more information about these customers. A sample of 50 credit customers is selected with data collected on the following five variables:

LOCATION (Rural, Urban, Suburban)
INCOME (in \$1,000’s – be careful with this)
SIZE (Household Size, meaning number of people living in the household)
YEARS (the number of years that the customer has lived in the current location)
CREDIT BALANCE (the customers current credit card balance on the store’s credit card, in \$).
The data is located under G-Drive, or your F-drive if copied before. In Minitab, click on file/open worksheet/Under G drive, go to MATH533, and open MATH533projectDataset.

1- Construct a pie chart for qualitative variable Location and explain what pie chart indicates in terms of proportion of account in different locations. See instructions A for Minitab step by step procedure. (Copy and paste the graph into this word document)

2- Construct Histograms of Income, Size, Years, and Credit Balance and describe the shape of these variables. (Copy and paste three graphs here) See instructions B.

3- Find the descriptive Statistics (mean, median, mode, standard deviation) on Income, Size, years, and credit Balance based on three categories of location. Describe differences on these variables based on location. (copy and paste here) See Instructions C.

4- Analyze the relationship between paired variables (income, credit balance), (size, credit balance), and (years, credit balance) using scatter plot and fitted line plot. In all graphs credit balance is the Response Variable. Explain the relationships and equations obtained. What does the slope of each line indicates? (copy and paste 3 graphs here)

5- Provide complete report as follows:

Brief Introduction
Discuss your 1st individual variable, using graphical, numerical summary and interpretation
Discuss your 2nd individual variable, using graphical, numerical summary and interpretation
Discuss your 3rd individual variable, using graphical, numerical summary and interpretation
Discuss your 4th individual variable, using graphical, numerical summary and interpretation
Discuss your 5th individual variable, using graphical, numerical summary and interpretation
Discuss your 1st pairing of variables, using graphical, numerical summary and interpretation
Discuss your 2nd pairing of variables, using graphical, numerical summary and interpretation
Discuss your 3rd pairing of variables, using graphical, numerical summary and interpretation
Conclusion
Minitab Instructions

A- Pie Chart Graph

In Minitab click Graph/pie chart/click in open box on the right side/click on C1 Location/select. Then click on label/slice labels/and check mark all boxes name, Frequency, percent /draw line. Then OK.

B- Construct Histogram

Click on Graph/Histogram/Simple/OK/ pick Income from list and select/ then OK. Copy and paste in the word file after part 2. Redo for other three variables for total of 4 histograms.

C- Finding Descriptive Statistics

Click on Stat/Basic Statistics/Display Descriptive Statistics/select all 4 variables/by Variable “C1-Location”/ Click on Statistics and in new window pick only 4 statistics from menu mean, median, mode, and std. deviation/Ok/Ok. Copy and paste in part 3.

D- Scatter Plot and Regression Equation

Click on Stats/Regression/Fitted Line Plot/ pick Credit Balance for Response and Income for predictor/Type of regression is linear/OK. Copy and paste in part 4. Must do two more scatter plots with changing the predictor to Size and then year. Total of three scatter plots needed.
