Graphs are used to show the relationship between related quantities.
The best type of graph to model the speed over the full two minutes, is a discrete graph.
From the question, we have the following variables:
The best type of graph must show the trend between the speed of the roller coaster and the time.
Analyzing the options, we have:
- Both variables are numerical data, and a qualitative graph cannot be used as a model; because qualitative graphs are used for non-numerical data.
- Bar graphs and histograms are used to show distributions; not trends
- The discrete graph (see attachment) is used for numerical data, and it can also be used to show trends (by connecting the dots)
Using the above analysis, we can conclude that the best type of graph to use, is a discrete graph
