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.
What is the meaning of dependent variable in research?
Definitions. Dependent Variable.
The variable that depends on other factors that are measured
. These variables are expected to change as a result of an experimental manipulation of the independent variable or variables. It is the presumed effect.
What is dependent and independent variables in research?
The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable. … The dependent variable is
the variable being tested and measured in an experiment
, and is ‘dependent’ on the independent variable.
What are examples of dependent variables?
It is something that depends on other factors. For example,
a test score
could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.
How do you identify independent and dependent variables?
You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an
experiment
, you manipulate the independent variable and measure the outcome in the dependent variable.
What is dependent and independent variable in research example?
In a study to determine whether how long a student sleeps affects test scores,
the independent variable is the length of time spent sleeping
while the dependent variable is the test score. … The independent variable in your experiment would be the brand of paper towel.
Which is the dependent variable?
The dependent variable is
the variable that is being measured or tested in an experiment
. … The dependent variable is dubbed dependent because it is thought to depend in some way on the variations of the independent variable.
What are 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
.
Which is another term for dependent variable?
Depending on the context, a dependent variable is sometimes called a “
response variable
“, “regressand”, “criterion”, “predicted variable”, “measured variable”, “explained variable”, “experimental variable”, “responding variable”, “outcome variable”, “output variable”, “target” or “label”.
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 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 are the characteristics of dependent variable?
A dependent variable is
what you measure in the experiment and what is affected during the experiment
. The dependent variable responds to the independent variable. It is called dependent because it “depends” on the independent variable.
What is dependent and independent variable in qualitative research?
The independent variable is the variable that is being manipulated, or the one that varies. It is sometimes called the ‘predictor’ or ‘treatment’ variable. The
dependent variable is the outcome (or response) 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.
How do you know if a variable is independent?
You can tell if two random variables are independent
by looking at their individual probabilities
. If those probabilities don’t change when the events meet, then those variables are independent. Another way of saying this is that if the two variables are correlated, then they are not independent.
What is independent variable in Research example?
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.
