64
98
96
93
70
97
74
67
63
71
80
57
77
43
78
52
65
92
53
87
62
66
50
Using yourstem and leaf plot identify the range of the data: _____________
B. Next create ahistogram to represent this data. You may choose as many bins as you wouldlike, though 10 is normally the ideal number.
a. Indicate thenumber of bins for your histogram: ________
b. What size shouldyour intervals be? Show your calculations: ______________________________
c. Fill out thefollowing table to indicate your midpoints and intervals, which will serve asbins
Midpoints
Bins/Intervals
Frequency
d. Use the tableyou constructed in part c to create your histogram. Label each part. Indicateyour intervals below the histogram and have each bin be two squares wide. Usethe graph paper below
e. Is the graphskewed? Is it unimodal or bimodal?
f.Are 10 bins appropriate in this circumstance? Does itshow enough variation in the data, or should be make fewer/more bins?
