How many variables can a scientist change in an experiment?

Answer 1

Anything that can be changed in any way is a variable. so,,,,,an infinite number.

Day, time, heat, light, humidity, speed, what you ate for dinner the Wednesday before you go shopping.

So, quite literally, an infinite number.

Hope this helps.

Answer 2

There are 3 variables in an experiment, basically. They are Dependent, Independent and Controlled variable.

Firstly,Dependent variable means the thing you want to observe.In other words,the scientist focuses his or her observations on the dependent variable to see how it responds to the change made to the independent variable. The new value of the dependent variable is caused by and depends on the value of the independent variable.

Independent Variable means the thing that you change while doing your observation.In other words,the independent variable is the one that is changed by the scientist.

And the Controlled Variable means the thing(s) you remain constant through your observation.

I wish this could be useful for you :)

Good luck

Answer 3

It depends on the experiment. The independent variable is what you "control" (change around) so as to produce different results from the dependent variable. Experiments must also have a control variable, or one that remains unaffected throughout the experiment, so that you can have something to compare your other results to.

Answer 4

The variables are The Independent ( X axis) and Dependent( Y axis

Answer 5

You can have any number of controlled variables. There is no limit. You can only have 1 UNCONTROLLED variable.

Answer 6

You should only change one variable at a time.

Answer 7

One at a time
