the only variables in an experiment are the independent variables [the thing in an experiment your going to change. and the dependent variables [the thing in an experiment your going to measure.
Variables that do not change in an experiment are independent variables.
Independent variables are variables that can be changed in an experiment, while dependent variables are variables that change as a result of an experiment. In other words, independent variables are what you change, and dependent variables are the results of the experiment.
The variables make the experiment more controlled
There are two types of variable, independent variables and dependent variables. Dependent variables are the type of variable that are changed in an experiment. Independent variables are not altered by the experiment.
It is important to Identify as many variables as possible in an experiment because variables change the answer/s. The more variables you identify, the easier it will be to prove your answer/experiment.
A variable affects the outcome of an experiment. The amount of a variable in an experiment will vary depending on the experiment and how many variables you want to effect it. Some variables can be controlled while others can not.
in a well tested experiment how many variables change
The control variables.
The controlled variables
Without variables, you have no experiment. You need variables in an experiment because without them you are left with multiple tests with an empty data table and no conclusion or discussion.
An experiment in which all variables stay the same is called a "controlled experiment".
Independent variablesDependent variables
yes it does
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!
Potential variables that are kept the same during an experiment are control variables.The values being altered and tested are experimental variables.
Variables work by telling you what you need to change, what to observe, and what to keep the same in a experiment.
the reason it is important to controll the variables in an experiment is because if the variables are not controlled in an experiment it will be impossible to reproduce the experiment. which also will make it impossible to prove the theory being tested
. Constant variables are variables which cannot be changed with the experiment. To remember their name is easy just think about Constance. They are important to an experiment because without all three variables there would be no complete experiment. Also the constant variables are important to an experiment because they help complete the result. Without a constant variable you. Would not be testing correctly
Everything in an experiment that can change in some way is a variable. The goal is to have a completely controlled environment where the only changing variables are the dependent and independent variables but often other variables change too. Experiments must have variables because otherwise there would be nothing to test in the experiment. In an experiment, it is the change in one variable that you are measuring.
The thing that you change, from experiment to experiment.
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.
