A. Brief Introduction:
There are 50 credit customers who were selected for the data collection on five variables such as location, income, size, years, and credit balance. In order to understand more about their customer, AJ DAVIS must used graphical, numerical summary to be able to interpret and better expand their business in the future. This report presents the findings of three individual variables extensively which include income, credit balance, and size. B. Discuss your 1st individual variable, using graphical, numerical summary and interpretation: INCOME

This histogram shows the distribution of data within the Income. In this Histogram graph of Income, it shows that the graph is not symmetrical. This histogram graph has a wider bell shape form. The graph shows that this graph is more like two graph because there is a clear difference between income generating from 20-40 and from 50-above. Mean = 43.74

StDev = 14.64

C. Discuss your 2nd individual variable, using graphical, numerical summary and interpretation : CREDIT BALANCE

A histogram shows the distribution of data within the Credit Balance. In this Histogram graph of Credit Balance, it shows that the graph is symmetrical with the exception of one outlier which is credit balance of \$2,000. This is a normal distribution with well-behaved tails and a single peak at the center of the distribution Mean = 3964.06

StDev = 933.49

D. Discuss your 3rd individual variable, using graphical, numerical summary and interpretation: SIZE

A histogram shows the distribution of data within the Size variable. In this Histogram graph of Size, it shows that the graph is not symmetrical. This histogram graph has a wider bell shape form. The skewness of this graph is skewed right. This graph shows that the size of two people per household is much higher than...
