Bar Graphs

A bar graph is a chart or graphical representation of data. A bar chart, also known as a bar graph, is a graph or chart that displays categorical data using rectangular bars with heights or lengths equal to the values they represent. Typically, bar graphs show categorical and numerical variables grouped in class intervals. A bar graph is useful for comparing and analyzing a set of data.

Question

For the following problem, suppose we have a collection of cars, we measure their weights and fuel
efficiencies, and generate the following graph of the
data. (Source:http://lib.stat.cmu.edu/DASL/Datafiles/carmpgdat.html)

Weight (100 lbs)
The strong association proves that more weight causes a lower mpg rating.
Higher vehicle weights are strongly associated with lower MPG rates, but this data set does not indicate that
higher vehicle weights cause lower MPG.
It makes sense that more gas is required to move heavier vehicles, so heavier cars cause lower MPG.
This data shows that to lower MPG and increase fuel efficiency, engineers need to design lightweight
vehicles.
