Grade 7/8/9 Data Management

The NCTM publication “Navigating through Probability in Grades 9 to 12” has an interesting data management activity called “One-Boy Family Planning”. Using the Chinese “one-child” family planning policy from 1979, students are asked to imagine that the policy says that families can have “one boy” rather than “one child”. A die is used to simulate the birth of a boy (odd numbers) or a girl (even numbers). Students run 20 simulations and track how many “children” are born before a boy occurs in each of the 20 simulated families.

I am using this activity as a make-up activity for students who didn’t do well in our initial data management and probability unit. Since the activity requires them to pool their data with other students, the attached document includes data for nine fictional students. The table can be selected, copied, and pasted into Excel. Students can also receive BTT10 marks for their use of Excel in creating the tally charts and graphs.

My data for you to use as you wish: oneboydata.doc
