Collect 50 or more quantitative (numerical) raw data items on a topic that interests you.

1. Is the histogram skewed left, right, bell-shaped, uniform, or symmetric? (See page 88 in your text)
2. Which is the most common class?
3. What conclusions can you make by observing the histogram?
4. 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.

1. Lastly, go back into StatCrunch and run some simple summary statistics on your data. List the Mean, Median and Mode(s) in your post. You can get these fromStatCrunchvery easily by running summary stats on your data. Watch this video for help:

3. Does the computed Mode match with what you SAW from the graphs? Discuss how and why they might be different
