Minute Math

##### Home Work by Mr. Reed
These short assignments are to provide excursions into the world of math which we encounter in everyday life and support some concept we are studying in class. While I refer to them as Minute Math Lessons the may take a little longer than a minute. I appreciate your work on these activities and the help you get from home.

Calculate the measures of center for your sample as well as the range and the mean absolute deviation. What is the difference between your age and the measures of center and what does this suggest about the ages of those you are close to? Also what does the range and the M.A.D. suggest about the variety in the ages of those in your sample?
