False

false

The independent variable, if there is one, is usually plotted on the x-axis, not the y-axis. So the question is based on false premises. The practice of putting the dependent variable on the vertical, y-axis is just a matter of convention. There is no mathematical justification for it.

False

False.

A variable does and must change, but you can only have one variable, otherwise the experiment becomes biased and unfair

Imagination is dependent. False autobiographical memories is independent.

true or false : in order to get the best results from an experiment, change as many variables as possible within the experiment?

independent variable

False. The control subject (Or control group) should be kept isolated from the variables of the experiment. This group will detemine if changing a variable is better or worse than not changing the variable.

First and foremost you must specify the hypothesis you are testing by the experiment. So you will have a testable null and alternate hypothesis. Next you will detail the resources and procedures used to generate the data needed by the tests specified by the hypothesis. Then using the described resources and procedures you will generate and record the data specified by the first two components. Next you will perform the analytic tests on those data, and record those results relative to the specifications made by your hypotheses. Following that you will write a summary of your results test and conclude whether your null hypothesis was shown to be not false based on you experimental results. Finally, you will write recommendations for further action and/or experiments based on your own experiment.

I found two answers for this question. A function is a rule that assigns to each value of one variable (called the independent variable) exactly one value of another variable (called the dependent variable.) A function is a rule that assigns to each input value a unique output value.
