You will be working with stem-and-leaf plots, frequency tables, and line plots with data generated by your class.
1) On a separate piece of paper, Mrs. Cook is going to time you to see how many stars you can draw in
30 seconds.
I drew ______________ stars
2) Mrs. Cook will assign you a number. Go to the Promethean and write down how many stars you
drew in the table next to your assigned number.

4) Place these numbers of stars in order from least to greatest:
5) Where does most of the data fall? Are there any outliers? If so, what are the outliers?

6) Make a frequency table of the class data. We will discuss making the intervals and cumulative
frequency together.
Interval Tally Frequency Cumulative
Frequency
7) What is the interval size for the class? How did you determine the interval size?
8) Last, but not least, make a histogram of the class data. Where does most of the data cluster?
