Is the histogram skewed left, right, bell-shaped, uniform, or symmetric? (See page 88 in your text)
Which is the most common class?
What conclusions can you make by observing the histogram?
Before answering this last question, you need to work with your data some more.
Open the “Histogram with Sliders” applet by doing the following: Click on the StatCrunch button (right above where it says Row), then on Applets, then on Histogram with Sliders. Select the same column as you did for your original histogram, and click on Create Applet.
Now, answer the following questions: If you modify the bin width (class width) using the slider, how does your histogram change? Can you make any new or different conclusions? Choose a bin width that tells you something new about your data.
