How do you describe variables in an experiment operationally?
Variables work by telling you what you need to change, what to observe, and what to keep the same in a experiment.
What is the difference between manipulated variables and controlled variables?
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!
The variables in an experiment that stay the same?
These "variables" are called independent variables or constant variables meaning that they are capable of being changed by the experimenter but are intentionally held the same through each individual experiment.
The difference between the independent and dependent 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.
Is it easier to control dependent variables than independent variables in a scientific experiment?
It is easier to control independent variables
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.
What are variables that do not change in an experiment?
Variables that do not change in an experiment are independent variables.
The variables that do not change in an experiment are what?
Variables that do not change in an experiment are independent variables.
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
What type of variables are in experiment?
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.
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.
How many variables does a properly designed experiment have?
One
