Abstract:
|
According to www.thewalkingsite.com, guidelines say we should walk 10,000 steps per day, which is close to 5 miles. A pedometer will keep track of the number of steps you take, but just how accurate is it? If the pedometer says 200 steps, did you really take exactly 200 steps? Does the brand of pedometer make a difference? I have developed activities that use pedometers in statistics classes for data collection and illustration of core statistical concepts. These activities help students see the usefulness of statistics in their everyday lives. They also help make students think about the benefits of physical activity. The activities give ideas on collecting data that can then be analyzed in class activities or on homework assignments. Activities that illustrate descriptive statistics, a confidence interval for the mean and the paired t-test will be discussed.
