We did a lab where we measured the power we use while running and walking a certain distance. We used meter sticks to measure the distance and we used stop watches to keep track of the amount of time it took for each of us to walk/run to the end of the meter sticks.
I don't see many places where I can wind up with errors in this lab so I need a little help to figure out some reasonable errors.

regarding stopwatch time errors:
human reaction time = 0.1 up to 0.4 seconds that would mean 0.2 s minimum error in timing to start and stop watch probably more like 0.4 to 0.5 seconds on average. This would definitely influence the outcome if the total times measured were less than 50 s. Once the time/s reach a minute or more the human reaction time error is less than 1%.

Biggest error will be in measuring time.
