Is sandpaper a dependent variable

Answer 1

I really can not answer this question. Variables represent outcomes, properties, qualities or events.

A good example of a dependent variable related to sandpaper is the amount of wood is removes.

Now, this variable will depend on many factors. Can you think of some?

a) The amount of time that you sand

b) The roughness of the sandpaper

c) The size of the piece of wood you are sanding

d) The hardness of the wood you are sanding

e) The pressure that you apply when you are sanding

I can come up with many more independent variables if I include sanding by hand or using a machine.
