Question

Given each scenario, identify an appropriate type of chart or plot discussed in class that you could use to determine the answer. (e.g. pie chart, scatterplot, etc.) a) A poll of 200 undergraduates was taken. The respondents were asked to list all the modes of transportation used going from their home to campus. Is the correlation between daily outside temperature and amount of natural gas used for heating positive or negative? We want to understand the Indiana yearly harvest (in tons) of soybeans between 1985 and 2015. We want to see if there is a relationship between the weight of a passenger vehicle and fuel efficiency (measured as miles per gallon). We want to understand the distribution of yearly household incomes in Tippecanoe County for 2012. We want to understand the distribution of cholesterol level for 100 males aged 20-30 What is the percentage of Indiana vehicles that are small passenger cars, large passenger cars, trucks, SUVs, and other types? b) c) d) e) f) g)

Explanation / Answer

a) A pie chart, as there could be many modes of transportation

b) To find correlation we use scatter plots.

c) Here we use a Histogram, as we are using yearwise data over a period of 30 years.

d) Again here to check a relationship, we use scatter plots.

e) Here since there are many households, to make sense of the data a scatter plot would be used.

f) Here we would use Bar Graphs, as there is a finite number of people and according to ages we can categorise the distribution.

g) Definitely a pie chart.
