1. Percent frequency distributions for each of the key variables: number of items purchased, net sales, method of payment, gender, marital status, and age. [Show the distribution’s graph as well] 2. A sorted bar chart showing the number of customer purchases attributable to the method ofpayment. 3. A crosstabulation of type of customer (regular or promotional) versus net sales. Comment on any similarities of differences observed. 4.A scatter chart to explore the relationship between net sales and customer age. 5.A chart to examine whether the relationship between net sales and age depends on the marital status of the customer. 6.A side-by-side bar chart to examine the method of payment by customer type (regular or promotional). Comment on any differences you observe between the methods of payments used by the different types of customers.

This data was collected from the members of our class. I have tried to remove anything that would identify an individual. 1. What is the scale of each variable? 2. Construct a frequency table and chart showing the distribution across gender in this class. 3. Construct a cross tabulation with Gender in one direction and Height in the other direction. Group the height category into 5 groups. 4. Is there a difference in the age distribution across gender? 5. Give a summary of our class based on this data about our class.   Gender Height Year Born Male 76 1994 Male 72 1983 Female 65 1997 Male 68 1966 Female 67 1997 Male 70 1996 Male 71 1996 Male 73 1996 Male 72 1995 Male 71 1998 Male 73 1993 Female 66 1980 Female 62 1998 Male 76 1984 Female 70 1985 Female 62 1992 Female 62 1992 Male 73 1996 Female 68 1987 Male 60 1971 Female 60 1971 Male 60 1971 Male 74 1970 Male 77 1998 Male 77 1998 Male 68 1990 Female 64 1996 Male 80 1997 Male…

The Big Mac index is a way of measuring Purchasing Power Parity (PPP) between different countries. By diverting the average national Big Mac prices to U.S. dollars, the same goods can be informally compared. The Big Mac can also be a good indicator for the individual purchasing power of an economy since he exists worldwide in standard size, composition and quality. Price # of Countries Rel. f.
