How many variables there be in an experiment?
As few as possible.
What are Confounding Variables?
In any experiment there are many kinds of variables that will effect the experiment. The independent variable is the manipulation for the experiment and the dependent variable is the measure you take from that experiment. Confounding variables are things in which have an effect on the dependent variable, but were taken into account in the experimental design. For example, you want to know if Drug X has an effect on causing sleep. The experimenter must take care to design the experiment so that he can be very sure that the subjects in the study fell asleep because of the influence of his Drug X, and that the sleepiness was not caused by other factors. Those other factors would be confounding variables.
What is being measured in a science experiment?
in a science experiment many things are measured. it depends on what experiment one is conducting.
How many independent variables should you have?
five
How many manipulated variable are in an experiment?
as many as needed
How many variables does a properly designed experiment have?
One
In a properly designed experiment how many mainpulated responding and controlled variables should you have why?
In a properly designed experiment, it is important to have at least 2 controlled variables. With two variables you are able to remove one at a time and see the effect in your setup.
How many variables does a controlled experiment have?
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.
How many variables are kept constant in a experiment?
All variables except one, the experimental variable, are kept constant in an experiment.
How many kindds of variables are there in a experiment?
5
How many variables can you test in an experiment?
one
How many manipulated variables can you have in an experiment?
1
How many variables there be in an experiment?
As few as possible.
How many variables do you investigate in a controlled experiment?
There are complex models that allow researchers to study several variables if the experiment is carefully designed and very carefully carried out. These models can show whether a variety of variable interactions occur, and if that is your focus then these models are good. But the best experiments investigate a small number of variables, as few as one.
How many variables are tested during an experiment?
There are three types of variables tested: manipulated variables, controlled variables, and experimental variables.
How many variables should have an experiment?
A experiment should only have one variable.
How many variables are supposed to be in a science experiment?
Most science experiments will have two independent variables. Fundamentally, an experiment will want as few variables as possible for better results.
