Peter Smith from Mechanicsburg High School in Pennsylvania shared
this nice activity that helps students see the value of regression
1) Get a copy of the top 10 movies from last year
2) Pair the students up and have each rank the 10 movies in his/her
own order of popularity. Do this independently of the partner.
3) Let one student list his/her preferences as the x-axis while the
other student's choices form the y-axis.
4) Make a scatter plot of the data.
5) Analyze the data:
a) The stronger the positive association, the more likely the
two students would enjoy going to the same movies together.
b) The stronger the negative association, the less likely they
would enjoy going to movies together.
c) If the association is weak, then they would obviously hit and
miss on their mututal movie enjoyment.
This is a nice little exercise but it does help students see how
regression analysis can be useful; especially, if this is extended to
other factors such as sports, favorite foods, hobbies, etc. It would
indicate good compatibility for dating.
