## Is there a relationship between a person's height and the length of his or her stride? |

The hypothesis - that the ratio of the height of a person to his or her stride does not vary much between genders and over different age groups - is proven to be true. Therefore, if we measure the height of a person, we can then quite accurately estimate his or her stride distance by dividing his or her height with the ratio of 0.4 as calculated in the table above.

The measurement of stride is necessary for pedometers. A pedometer measures the number of steps that we take in a specified span of time. If we know our stride distance, then the pedometer will be able to tell us the distance we have walked in the specified time.

The experiment can also be done by comparing strides when walking barefoot,, and then when walking with slippers and with shoes.

This experiment can also be repeated using different age groups consisting of people in their 20's, 40's and 60's. Also, it would be interesting to know if people from difference races or geographical regions have different stride lengths.
