I demonstrated the variables in a dot plot to illustrate the number of years the customer has been living in that location. The most years was more than 18 years and the location was in an urban area. The highest amount of dots was 10 years. The shape of the distribution is symmetric. The last pairing of variables I combined together is Income and Size and it demonstrated in a scatter plot. The household size of 7 or 8 has the highest income is with over $69,000 and more. The shape of distribution is positive linear relationship.
