How many variables can be tested at the same time in an experiment?

Potential variables that are kept the same during an experiment are control variables. The values being altered and tested are experimental variables.

An experiment of any kind can have infinitely many variables. A controlled experiment can have just as many, provided that all but one are kept exactly the same.

An experiment in which all variables stay the same is called a "controlled experiment".

These "variables" are called independent variables or constant variables meaning that they are capable of being changed by the experimenter but are intentionally held the same through each individual experiment.

If they are supposed to affect the results in the experiment ie. they are what is being tested, they are the test variables. If they must be kept the same to ensure a fair test ie. the scientist is not testing with them, they are called control variables.

things in an experiment that stay the same are called constants.

The factors that are kept the same in an experiment are the constants. The factors that aren't kept the same in an experiment are the variables.

They are the same. These are names for the variables in an experiment that are controlled by the experimenter, as opposed to the output variables, the results you collect at the end of the experiment Hope this helped!

Controls are the things you leave the same when you do an experiment. Variables are the things you affect in an experiment to see if it makes a difference. It depends on the experiment how you would "control" the variable.

The controlled variables.

A controlled variable is the variable that always stays the same when you change other variables in the experiment. A variable is an ingredient or way of doing something in an experiment.

It is important to use the same amount of water each time you conduct the experiment because if you change more than 1 thing in an experiment, then you can't know the true result because you tested too many things. You need all controlled variables in an experiment except for 1 manipulated variable.

The general term is 'controlled experiment'.

It can have as many as it needs. You can even change different variables at the same time and study their individual influence with proper statistical tools in many type of experiments.

standardizing variable is what stays the same in an science experiment.

It is important to have controlled variables in a scientific experiment because it is the variable that remains the same it doesn't change. Its a consent & can be measured against.

Ideally, an experiment should test only one variable (the independent variable) at a time. If you have two or more variables changing at the same time you have no way of knowing which variable is causing your results.

The parts of an experiment that stay the same are known as the controls. The parts that change are called variables (hence they vary).

When a scientific experiment is carried out in a controlled setting, all variables are kept the same except for the control variable. The control variable is something that is constant and unchanged in an experiment, and is held constant to test the relative impact of independent variables.

The control is the variable that stays the same. The independent variable is the thing(s) that is being changed in the experiment. (don't have too many independent variables o your experiment will not work correctly). The dependant variable is the variable that depends the on the independent variable for the experiment.

If you documented all your results, had a partner, had a witness, completed the experiment many times with the same results, and tested the experiment on the proper things then this would be good validation.

Any amount can be changed as long as one stays the same

When a scientific experiment is carried out in a controlled setting, all variables are kept the same except for the control variable. The control variable is something that is constant and unchanged in an experiment, and is held constant to test the relative impact of independent variables.

It differs in the one variable being tested
