You will need a calculator, a ruler, and a piece of Centimeter Graph Paper to answer Questions 16–21.
Check-In: Question 16
- After Mrs. Dewey's class finished the experiment Downhill Racer, they did another experiment using ramps. In the new experiment, each group kept the height of the ramp the same and used the same car all the time. They chose three distances from the end of the ramp for starting points. Then they rolled the cars down the ramp from each starting point and measured the distance the car rolled in centimeters. Here is one group's picture of the experiment.
- What is the manipulated variable in this experiment?
- What is the responding variable in this experiment?
- What are the fixed variables?
- Is the manipulated variable numerical or categorical?
- John's group rolled its car down the ramp three times from the starting point that was 60 cm from the end of the ramp. Here are the distances the car rolled for three trials: 83 cm, 84 cm, and 89 cm. What is the median distance?
