I'm doing a biomechanics lab report, and have got loads of numbers to crunch. i;ve got to a point where my mathematical knowledge is letting me down.
I've got two data sets: displacement and time, with 5 sets of results for each.
Why when I work out the average displacement over average time, do I get a different results for each displacement over time divided by 5?
If that makes sense

is the gradient of the graph changing? i.e. is the graph a curved line? can you write out the data in a table so that I can look at it?

I'm not doing graphs atm, just raw data.
I'm using angular displacement/time to work out angular velocity, if thats any help.
I have a mean angular velocity worked out using each (displacement/time)/5, and when I work out average angular velocity/averge time, it works out differently. Which one is theoretically correct?

If this is any help:
I'm working out angular velocity, which is change in displacement/time.
