Your boss would like your help on a marketing research project she is conducting on the relationship between the price of soda and the quantity of
soda demanded. She hands you the following document:
Price of Soda
Quantity of Soda Demanded
(Dollars per can)
(Billions of cans)
0.50
2,000
0.75
1,500
1.00
1,000
1.25

Your task is to take this
and construct a graphical representation of the data. In doing so, you determine that as
the price of soda rises, the quantity of soda demanded decreases. This confirms the
A researcher wants to study about the behaviours of postgraduate students in Australia in mobile phone usage.
One of the goals of the study is to analyse whether there is a relationship between the type of apps that the students use the most and the degree they are studying.
What is the most suitable graph to see the relationship described above? Why?
