question when doing a simple investigative experiment...

should such variables as mass be similar to each other? what would be the advatages? disadvantages?

I said that the masses really shouldn't be similar...you're trying to get a data spread and you want your masses to not be similar but evenly spread...How right or wrong am I?

THX :)

Can you please be a little more specific? Variables depend on what kind of experiment you performed, because in some cases, things like mass are not inconsiquential. Can you go into a bit more detail about your experiment?

We don't know what your experiement is, but generally if you want a data spread you (a) increase the number of sample points and (b) increase/decrease the distance (call it distance, span or delta...whatever) between successive values as desired.

So if you want a spread in mass, you could just add more mass...or to be more precise, add more weight (since you can't determine mass accurately anyway :tongue2:). Oh well, that's perhaps the most hopeless advice I can give you under the circumstances.

Advantages/Disadvantages? We don't know that until we know the objective of your investigation.
