4. TOP USA ROLLER COASTER SPEEDS Dear _________________, You have made a very accurate box plot, stem n leaf plot, line plot and histogram of the roller coaster data, but I really only have enough time to present one graph to our supervisor. Please use your best judgment in choosing the graph for Mrs. Complains-a lot. The graph you choose must display enough of the data to a good picture of what the data set is telling us about the roller coasters in the USA. It must also be in an easy to read format as Mrs. Complains-A lot is very picky about displaying data. Use the checklist below to help make your decision: Now, that you have thought about each graph, decide on which one you will present to the picky Mrs. Complains-A lot. Use the rubric on the back of this sheet to help you write a letter convincing Mrs. Complains -A lot to choose the same graph you did. Graph or Plot Type: Line Plot Stem N Leaf Plot Box Plot Bar Graph Histogram Shows the mean of the data set Shows the median of the data set Shows the mode of the set of data Shows the maximum data point Shows the minimum data point Shows the clusters or gaps in the data Shows how far the data is spread out Shows outliers Is easy to read and understand Shows the data in equal intervals Shows categories like favorite roller coaster Shows only a few data points from the whole set of data Shows all of the data in the data set
