A valid one. An experiment cannot conclusively prove anything if more than one independent variable is altered at a time. That being said, many dependent variables could show change and the experiment would still be valid, as long as only one independent variable was altered at a time. An experiment that changes only one variable at a time is called a controlled experiment.
What else can I help you with?
Which word goes with this definition procedure conclusion variable or theory What is a factor that changes in an experiment proper procedure calls for testing only one of these at a time?
This is a variable. Vary means change.
What is a factor that cannot be changed during a experiment?
A constant factor is one maintained unchanged throughout an experiment so that it does not affect the outcome. These are also referred to as controlled variables.
What is the factor being measured in a controlled experiment?
independent variable
In an experiment the factor that is deliberately manipulated also called the manipulated variable?
In an experiment, a factor or condition that is deliberately manipulated in order to determine whether it causes any change in another behavior or condition is an independent variable. The factor or condition that is measured at the end of an experiment and is presumed to vary as a result of the manipulations of the independent variables is called the dependent variable.
What is a variable for in scientific experiments?
A variable is anything which can vary, such as the length of time allowed for the experiment, the temperatures of the reactants, the pressure under which the experiment is taking place, the states of matter of the reactants (liquids, solids, gases) and the concentrations of any solutions being used.
What do we call an experiment in which only factor is allowed to vary?
A controlled experiment.
What is the constant variable?
factors in an experiment that are kept the same and not allowed to change or vary.
What Factor does not vary in a experiment?
The control variable, also known as the constant variable, does not vary in an experiment. It is kept constant to ensure that any changes observed are the result of the independent variable being tested.

Why most only one variable change in an experiment?
That is simply not true.There are times when a number of factors can have an effect on the outcome of an experiment but it is not possible to conduct the experiment so that only one factor is allowed to vary while all others are controlled. It is far more efficient - in terms of experimental units - to design the experiment so that the interactions between variable factors can be estimated. Experimental design is the subject that deals with the problem of designing efficient schema for dealing with a number of interacting factors. You may wish to look at "Latin square design" and "Greco-Latin squares" as an introduction to design.

Alternator Power factor 0.8 why?
its vary between 0 t0 1 only .....pf =0.8
Why can there only be one variable in an experiment?
If you vary only one quantity in an experiment, then the results will be related to that quantity. If you vary two or more quantities, then the results will be ambiguous; you will not know what variation is responsible for the observed result.
