For my project I am going to ask people at the gym to see how many reps of 135 pounds they can do and then see how much the weight. I want to se if they reps a lifter can do is dependent on they weight of the lifter.

I have chosen a weight of 135 pounds because it is a relatively small weight. This will allow me to get a full 30 people in the study. Also I made sure to have people do it before they started their workout to make sure they all started fresh.

Here is the data I received:

After reviewing my data it is clear that the weight of the lifter allows them to do more reps of 135 pounds. In few cases a person weighing less could lift more than a heavier person. I think this happened because people are at different stages in their training. For example a person who may weigh less could have been training for longer than a heavier person and still lift just as much.
