Want this question answered?
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.
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.
a fair test is were you only change one thing
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.
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.
A fair test is when you test something equally changing the variables but keeping everything else the same
it is a fair test

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 :)
A fair test is something that doesn't change in a test for a plant.
Generally speaking, you only want to test a single variable within one experiment so when a change occurs you know what caused it. If you change multiple variables at once it is harder to attribute the change to a single cause.
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.
