The frequency distribution and Bar chart are given as follows: Frequency Distribution: | | Location | Frequency | | Urban | 22 | | Suburban | 15 | | Rural | 13 | | | | |   From the frequency distribution and bar chart, it is clear that the maximum number of customers belongs to the urban sub-category (44%), followed by those in the suburban sub-category (30%).  Only 26% of the customers belong to the rural sub-category. The next variable considered is Size. It is a quantitative variable. The measures of central tendency, variation and other descriptive statistics have been calculated for this variable and are shown below: Frequency Table | Value | Frequency | Frequency % | 1 | 8 | 16.00 | 2 | 7 |......

...Maurice S. Butler Math533—Applied Managerial Statistics Course Project: Part A Introduction This project is based upon statistical data compiled concerning AJ Davis Department Stores, specific to a sample of its customer base. It is with intent of establishing relationship between location, gross income, and credit balances carried by customers that the following statistical analysis has been performed. It is assumed that information obtained as well as the interpretation of statistical analysis will enable credible recommendations in regard to future revenues or continued handling and/or maintenance of its receivables. Variables The first variable is the gross income of the stores’ customers. The data set includes 50 customers with gross income ranging from $20,000 to $79,000 per year. Compilation of the data into a frequency/relative frequency table (see below) reveals that the greatest frequency and relative frequency of the store’s customers is found within the $30,000 to $49,000 range. Fifty-two percent of the store’s customer base gross income is found within this range. First and third quartiles have been calculated to be 33 and 57 respectfully. However, no outliers have been identified within the data set. Income ($1000) | Frequency | Relative Frequency | 20-29 | 5 | 10% | 30-39 | 13 | 26% | 40-49 | 13 | 26% | 50-59 | 8 | 16% | 60-69 | 9 | 18% | 70-79 | 2 | 4% | | 50 | 100% | My second variable is the outstanding credit balances of...

However, the rural and suburban area accounts for over a quarter of the credit holders. This shows that although the major of credit customer resident in urban areas, it is important to cater to the rural and suburban customer as well. This will maintain current credit customers and can increase the number of credit customers in the store chain. The 2nd individual variable I will discuss is Income: Descriptive Statistics Mean 43.74 SD 14.63963 Variance 214.3188 As shown in the descriptive statistics, the mean income is 43.73,000 for credit customers.
