For my engineering class I had to make a while loop to find the average of a data set and use tic/toc to time the process. My code is posted below but for some reason when I run tic/toc it says it takes 7 seconds. I'm just not sure this is right because a few of my classmates told me theirs was around 1 second and when I time it myself it doesn't take 7 seconds. If someone could tell me where my error is if there is one I would appreciate it!

You have not given us any information about what Average does.

You could improve your performance by calculating length(y) once before the loop and using that variable. With your current code it needs to recalculate length(y) every step.
