1. Arrange your data into an array.
2. Select your intervals. Explain your rationale for the intervals you selected.
3. Construct a frequency table. Remember, your frequency table should include class interval, frequency, relative frequency and cumulative relative frequency.  
4. Construct a histogram based on your table. Hand-drawn histograms are fine–maybe preferable. Be sure to follow all of the steps in the module.
5. Construct a frequency polygon based on your table. Hand-drawn polygons are fine–maybe preferable. Be sure to follow all of the steps in the module.
6. Find the mean, median, and mode for the data.
7. Is the data in question 2 skewed? Why or why not?
8. Pretend you are emailing your friend about the “O” virus. What would you say?
