On The Move
Question: Which type of transportation (car or bus) do you us and how often?
Sample: Math III class
Here are the data collected from the survey in two graphs.
The first one describes of the satisfaction in cars in a box-and-whisker plot.
The second one describes the satisfaction in busses in a histogram.
The next section are data collected from Math III class. The question was if you had and golf cart to take you from class to class, what would be the appropriate speed (from 1 to 100) and the appropriate price for the rental fee (from $10 to 50).
The box-and-whisker plot represents the speed.
The histogram represents the rental fee.
If you haven't notice both of these surveys are biased because just one class doesn't represent the whole school or community.
