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.
Now I must choose the independent and dependent varaiable in the experiment and I'm unsure....help?
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.
To determine the independent and dependent variables in your experiment, let's break it down:
In your experiment:
Independent variable: The independent variable is the factor that you intentionally change or manipulate. In this case, the independent variable would be the number of coil wire turns around the nail. By changing the number of coil wire turns, you are controlling this variable.
Dependent variable: The dependent variable, on the other hand, is the factor that you measure or observe to determine the effect of the independent variable. It is the outcome or the response that you expect to change as a result of manipulating the independent variable. In this case, the dependent variable would be the number of paper clips that stick to the nail.
So overall, the independent variable in your experiment is the number of coil wire turns around the nail, and the dependent variable is the number of paper clips that stick to the nail.
To summarize, the independent variable is what you change, and the dependent variable is what you measure or observe as a result of that change.
