1. how would you draw a stem and leaf diagram for each of theabove data sets.
2.Using your stem and leaf diagrams, make at least 2 commentsabout each set of data (i.e., what does the diagram tell you aboutthe data?).
3.For each of the data sets:
a.Create a histogram from the data.
b.Does the histogram tell you anything that wasn’t evident fromthe stem and leaf diagram? Does it make anything about the datamore difficult to see?
c.Create a second histogram with a different bin width. How doesthis change how you interpret the data?
4.For each of the data sets, explain whether you prefer the stemand leaf diagram or a histogram and why?
