Why is it important to test one variable at a time in an experiment?
If you change more than one variable at a time, you will not be able to tell which variable is responsible for what change. Scientists need to know exactly which variable caused the observed experimental results.
How can you find the independent and dependent variable?
Sometimes, with two variables, X and Y, you may have a causal relationship which means that a change in one variable, X, will cause a change in the other, Y, but there is no causal relationship in the other direction. In such a case X is the independent variable and Y is the dependent. For example, if you are studying the age and height of young children, both variables increase together: the older the child is the taller it is. The causal relationship is clear: the age of the child affects its height. Even though there is a clear correlation, the height of a child does not cause it to become older. Sometimes you can have two variables that are interdependent so that neither is independent. One possible example, from economics, is profit and capital investment. Higher profits should result in higher investment while higher investment should result in higher profits. Which one is the cause and which one the effect? You can also have a situation where two variables, which are correlated, but neither is dependent on the other: both are dependent on some other variable. For example, in the UK, sales from ice cream vans are correlated with seaside swimming accidents. Eating ice cream does not cause swimming accidents, nor do people who have had swimming accidents console themselves with ice cream. These two dependent variables are associated with the [hidden] independent variable: warm weather (or temperature).
Which of the follwing terms describes a variable that does not change in an experiment?
Constants
What was the colour of the Artemis the greek goddesses eyes?
Artemis like any Greek deity, could change her physical appearance including eye color.
A factor in a experiment that can change?
There are different types of factors that can change in an experiment. The environmental factors may change, and are out of your control. The variables in the experiment may also be changed but, are usually controlled by the individual conducting the experiment the majority of the time.
What appearance does a graph line have if the dependent variable doesn't change with time?
A horizontal line
What appearance does a graph line have if the dependent variable does not change with time?
It would be a straight horizontal line like this ______________________ ;)
What causes change in a dependent variable?
The dependent variable is dependent on the independent variable, so when the independent variable changes, so does the dependent variable.
Is the independent variable the one that does not change?
No, as the name Variable implies, it can and does change. Since it is 'Independent' its change is not a direct effect of the change of any other Variable. Additionally, the independent variable depends on the dependent variable.
Does elasticity measure the responsiveness of an independent variable to change in a dependent variable?
It measures responsiveness of a dependent variable to change in an independent variable.
A factor that is manipulated you an experiment to change the dependent variable is the?
in dependent variable
What is the definition for a dependent variable?
an dependent variable is one that you change in an experiment
Independent and dependent variable?
Math: Independent variable is what you change. Dependent variable is what you measure.
4 What is dependent variable and independent variable?
change and no change
What is the dependent and independent in a experiment?
The independent variable of an experiment is the variable that you change, and the dependent variable is the result of the independent variable.
Does the independent or dependent variable change?
The Independent variable is the one you control. The dependent variable is controlled by the Independent Variable.
What are independent and dependent variables?
The independent variable is also called an experimental variable. It is the variable being manipulated in the experiment in order to show the effect on the dependent variable. The dependent variable is also called the response variable. It is the variable being observed in the experiment. A change in the independent variable is what causes the change (if any) in the dependent variable, which is the purpose of the experiment.
