How many pieces of data, or observations, does Jerome have?
Refer to the data.
Make a stem-and-leaf plot of the data.
Jerome wants to present the data with a plot that makes it possible to calculate the mean and the median. Can he do this with a stem-and-leaf plot? He is not asking you to calculate them, but he wants you to tell him if it is possible and why.
Does the stem-and-leaf plot show all of the data points?
Use the stem-and-leaf plot to describe how the data is spread. That is, is it spread out, or is it concentrated mostly in a narrow range?
Where are most of the values concentrated?
Would it be helpful for Jerome to create a dot plot to display and analyze the data from problem ? Why or why not?
Would it be practical to put this information into a dot plot?
No, there are too many data points that do not repeat.
