What variables in an experiment which must remain the same in order to perform a fair test of the independent variable?
Variables that should remain the same in an experiment to have a fair test of the independent variable are called control variables. These include factors such as temperature, time of day, equipment used, and method of measurement. By keeping these control variables constant, any observed effects in the experiment can be confidently attributed to changes in the independent variable.
What are the factors that can change in an experiment called?
Environmental factors if you cannot control them.Variable factors if you can control them.See link below for easy explanation:In an experiment the scientist is able to change the independent variable. To insure a fair test, a good experiment has only one independent variable. As the scientist changes the independent variable, he or she observes what happens. - See more at: http://www.chacha.com/question/what-part-of-an-experiment-is-the-factor-that-you-change#sthash.iyH25Jac.dpufIn an experiment the scientist is able to change the independent variable.

What variable that remains the same so that the test is fair?
A constant variable is a variable that remains the same throughout the experiment to ensure fairness and accuracy of the results. It is used as a baseline for comparison with the changing variables being tested.
What variable did you change in your experiment?
I changed the independent variable in my experiment, which is the variable that is intentionally manipulated or changed to observe its effect on the dependent variable. This change allows for me to test the relationship between the variables and analyze the outcomes of the experiment.
What is required to make a test fair?
To make a test fair, it should be free from bias, have clear instructions, cover all relevant material, and be administered consistently to all test takers. This ensures that each test taker has an equal opportunity to demonstrate their knowledge and skills.
What is fair test?
A fair test is when you test something equally changing the variables but keeping everything else the same
What is fair testing in science?
Fair testing is when you test something with many variables, but you must change one variable. e.g. testing the different types ofdrinking water. [Tap water, hose water, etc.
When a experiment only has one variable that can change and all other variables are kept unchanged this type of experiment is an?
it is a fair test
What is a controlled variable in a science fair project?
It is the variables you will not change to keep the experiment a fair test, they should be kept constant to show how your independent variable affects your dependant variable.
How do the test variables and outcome variables in an experiment compare?
Test variables are the factors that are intentionally changed or manipulated by the researcher in an experiment, whereas outcome variables are the factors that are measured and affected by the test variables. Test variables are the independent variables that are controlled by the researcher, while outcome variables are the dependent variables that change in response to the test variables. The relationship between the test variables and outcome variables is explored to determine the effect of the test variables on the outcome variables.
What is a cotrolled experiment?
It means that except for the independent variable (the only factor that you change) you remain the other variables constant. To keep the control variables the same. Then this is a controlled experiment (fair test). Hope this helps :)
How many independent variables should an investigation have?
There can only be one independent and one dependent variable. All other variables should be classed as control variables and must be kept constant to achieve a fair test.
What is the meaning of fair test in science?
a fair test is were you only change one thing
What is a control variable in a science project?
It is the variables you will not change to keep the experiment a fair test, they should be kept constant to show how your independent variable affects your dependant variable.
How many variables can be changed in a fair test?
Only one at a time, since you would not know which variable(s) made the observed changes. You would need to measure each change separately. But if you want to test multiple variables, then you would need to test every possible permutation. If you want to test two chemicals, then you should test your control (a placebo using neither substance), substance A, substance B, and both substances.
What is a plant fair test?
A plant fair test is a scientific experiment that is conducted to test the effects of one independent variable on a plant, while keeping all other variables constant. This helps to ensure that any observed changes in the plant are due to the manipulated variable and not to other factors. It is a way to provide reliable and unbiased results in plant research.
Define a fair test?
A fair test has many differences from an unfair test. For example, a fair test is where if you have studied, there would be question-related to what you have gone through like if you are learning density, you would learn how to calculate it. But if the questions are unrelated to your research or what you have been tasked/ assigned, then that would be unfair and therefor wrong.
