So I did a science experiment and I have to wrap a coil wire around a nail and tap the other end to a battery. Then see how many paper clips will stick to the nail, and I had to wrap more coil wire around the nail over time and stuff and record the data.

Question

Now I must choose the independent and dependent varaiable in the experiment and I'm unsure....help?

Answer 1

An independent variable is the potential stimulus or cause, usually directly manipulated by the experimenter, so it could also be called a manipulative variable.

A dependent variable is the response or measure of results.
