Answer: An independent variable is exactly what it sounds like. It is
a variable that stands alone and isn’t changed by the other variables you are trying to measure
. For example, someone’s age might be an independent variable.
What is the independent in an experiment?
The independent variable (IV) is the
characteristic of a psychology experiment that is manipulated or changed by researchers
, not by other variables in the experiment. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable.
What is an example of an independent variable?
For example, in an experiment about the effect of nutrients on crop growth: The independent variable is
the amount of nutrients added to the crop field
. The dependent variable is the biomass of the crops at harvest time.
What is the independent and dependent variable in an experiment?
Independent variables (IV): These are
the factors or conditions that you manipulate in an experiment
. Your hypothesis is that this variable causes a direct effect on the dependent variable. Dependent variables (DV): These are the factor that you observe or measure.
What is a dependent variable in an experiment?
The dependent variable is
the variable that is being measured or tested in an experiment
.1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores, since that is what is being measured.
Which is dependent variable?
Answer: Just like an independent variable, a dependent variable is exactly what it sounds like. It
is something that depends on other factors
. … (Independent variable) causes a change in (Dependent Variable) and it isn’t possible that (Dependent Variable) could cause a change in (Independent Variable).
How do you identify an independent variable?
The
independent variable always goes on the x-axis, or the horizontal axis
. The dependent variable goes on the y-axis, or vertical axis. As you can see, this is a graph showing how the number of hours a student studies affects the score she got on an exam.
What are some examples of independent and dependent variables?
Independent variable causes an effect on the dependent variable. Example:
How long you sleep (independent variable) affects your test score
(dependent variable). This makes sense, but: Example: Your test score affects how long you sleep.
How do you manipulate independent variables?
Again, to manipulate an independent variable means
to change its level systematically
so that different groups of participants are exposed to different levels of that variable, or the same group of participants is exposed to different levels at different times.
What are the 3 types of variables?
These changing quantities are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables:
independent, dependent, and controlled
.
What is the difference between a dependent and independent variable?
In analytical health research there are generally two types of variables. Independent variables are what we expect will influence dependent variables. A Dependent variable is what
happens as a result
of the independent variable.
What is a sentence for dependent variable?
Two multiple regression analyses were performed with each contraceptive measure as a dependent variable. The dependent variable
here was equal to 1 if the women had ever used a medical method and zero otherwise
.
What is the factor that changes in response to the independent variable?
The dependent (or responding) variable
is the one that is observed and likely changes in response to the independent variable.
Can time be a dependent variable?
Time is always the independent variable
. The other variable is the dependent variable (in our example: time is the independent variable and distance is the dependent variable).
What is an example of an experimental variable?
Examples of common experimental variables are:
disease
.
compound
.
genotype
.
Is a control an independent variable?
It is also known as a constant variable or simply as a “control.” The control variable is not part of an experiment itself—it is
neither the independent nor dependent variable
—but it is important because it can have an effect on the results.
