Making Predictions Using a Spinner

Project #1467 on iSENSEProject.org

The project I have created has students work with a partner to spin an online spinner 10 times, using this link:

Before we get started let's answer the following discussion questions:

-What is the purpose of a spinner?

-How many possible outcomes are there with this spinner, and what are they?

-Is there an equal chance of obtaining each outcome? Why or why not?

-If you spin the spinner 10 times, what would you expect your outcomes to be? Why?

Directions:

Work with your partner, and spin the electronic spinner 10 times, and record your results on the tally sheet provided. Then search for project 1467 and manually enter your data onto iSense, using the contributor key cgs1234. Make sure to type in all group member's names as contributors!

After you have entered your data, first change your y-axis to "select all", then answer the discussion questions below with your group/partner:

-Was your original prediction correct? Why or why not?

-What variables might affect your outcome?

-How might the outcomes change if we weren't using an electronic spinner?

Now refresh your data so you can see class's data, and let's discuss the following questions:

-How did the visualization change from looking at just your distribution, to looking at all students' data? Did everyone get the same results?

-On the group setting, change "data set name (id)" to "combined data". How has the visualization changed now?

-What might happen if 100 people entered their data? 1,000? 1,000,000?
