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.
How do you identify the dependent variable?
Which Variable Does the Experimenter Manipulate? One way to help identify the dependent variable is to remember that
it depends on the independent variable
. When researchers make changes to the independent variable, they then measure any resulting changes to the dependent variable.
How do you identify variables in research?
A variable in research simply refers to a person, place, thing, or phenomenon that you are trying to measure in some way. The best way to understand the difference between a dependent and independent variable is that the
meaning of each is implied by what the words tell us about the variable you are using
.
What are independent and dependent variables in research?
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.
How do you identify the independent and dependent variables in a research topic?
- The independent variable is the cause. Its value is independent of other variables in your study.
- The dependent variable is the effect. Its value depends on changes in the independent variable.
What is variable in research example?
In research, variables are
any characteristics that can take on different values
, such as height, age, species, or exam score.
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
.
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 difference between dependent and independent variable?
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 is the independent variable in a research study?
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 are some examples of independent and dependent variables in healthcare?
For example: In a study of how different doses of a drug affect the severity of symptoms, a researcher could compare the frequency and intensity of symptoms when different doses are administered. Here the
independent variable is the dose and the dependent variable
is the frequency/intensity of symptoms.
How do you remember independent and dependent variables?
Many people have trouble remembering which is the independent variable and which is the dependent variable. An easy way to remember is
to insert the names of the two variables you are using in
this sentence in they way that makes the most sense.
What is an example of a qualitative variable?
A qualitative variable, also called a categorical variable, is a variable that isn’t numerical. It describes data that fits into categories. For example:
Eye colors
(variables include: blue, green, brown, hazel).
What are the 5 types of variables?

- Dependent variables. …
- Intervening variables. …
- Moderating variables. …
- Control variables. …
- Extraneous variables. …
- Quantitative variables. …
- Qualitative variables.
