Steps vs. Height Experiment

A week ago my daughters and I did a simple experiment to determine if there was a correlation between a person's height and the number of steps a person takes to travel a specified distance.  Our hypothesis was yes.  Taller people have longer legs and can travel a farther distance per step than a shorter person.  To test this out, we each walked from the front of the house to the back, counting our steps.  Here are our results graphed.

I plotted our heights versus the number of steps it took.  As expected, the greater the height, the fewer the number of steps. As you can see from the graph above, the 3 of us had a close correlation between the number of steps and height.  We then tossed my wife into the mix, used the above data to predict her height based on steps, and found she was 4 inches too tall!  So not a perfect correlation but it was a fun activity to do with the kids.  It was fun discussing with them and seeing their faces as they thought through reasons why Daddy takes less steps to reach the back of the room!
