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 ). 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.
