1. Draw a stem and leaf diagram for each of the above data sets.

2. Using your stem and leaf diagrams, make at least 2 comments about each set of data (i.e., what does the diagram tell you about the data?).

3. For each of the data sets:

a. is it possible to draw a histogram from the data.

b. Does the histogram tell you anything that wasn't evident from the stem and leaf diagram? Does it make anything about the data more difficult to see?

c. if conducting asecond histogram with a different bin width. How does this change how you interpret the data?

d. For each of the data sets, explain whether you prefer the stem and leaf diagram or a histogram and why
