Create a data table like the one below.
Have several people of different ages and genders try out this experiment.
Record their information in the data table.
Now divide your data into two categories (it might help if you make two new data tables, but you do not have to).
Organize the data by age (you can make groups- under 12, 12-18, 18-25, 25 )
The Effect of Age on the Ability to Do the Chair Trick
On one graph, you will have 4 bars- two for females and two for males. For each gender, show the number that could stand up with the chair, and the number that could not stand up with the chair.
On the second graph, you will have two bars for each age group- one will show how many could stand with the chair, and one will show how many could not stand with the chair.
The numbers up the side (vertical Y-axis) will be the numbers of people.
Make sure your graph is correctly done (refer to your handout on bar graphs for correct format).
Using complete sentences, answer the following questions:
(1) Which variable seems to most affect a person's ability to do the chair trick? Explain your answer using your data to support your reasoning.
(2) If I told you that a person's "Center of Gravity" played a role in his/her ability to do the chair trick, how would that help to explain your results? Be specific in your answer and, once again, use your data to support your reasoning.
