What are independent variables in psychology?

The independent variable is the variable that is manipulated by the experimenter. For example, in an experiment on the impact of sleep deprivation on test performance, sleep deprivation would be the independent variable.

What is the independent and dependent variable in psychology?

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 the independent variable in a psychology 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 psychology?

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.

What is an example of dependent variable in psychology?

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. In a psychology experiment, researchers study how changes in one variable (the independent variable) change the dependent variable.

Psych Terms: Independent and Dependent Variables

How do you identify an independent variable?

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. Other factors (such as what they eat, how much they go to school, how much television they watch) aren't going to change a person's age.

How do you remember independent and dependent variables?

An easy way to think of independent and dependent variables is, when you're conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as the effect.

What is an independent variable in psychology quizlet?

Independent variable. The variable that the researcher manipulates or changes (in an exam you should give both conditions).

Which of the following best describes an independent variable?

The factor that's changed by the experimenter and impacts the dependent variable best describes an independent variable.

What is an example of an independent variable research quizlet?

Examples: If a scientist conducts an experiment to test the theory that a vitamin could extend a person's life-expectancy, thenthe independent variable is the amount of vitamin that is given to the subjects within the experiment.

What is the independent variable in experimental research quizlet?

The independent variable is the research variable that is manipulated in an experiment to test its impact on another variable. The dependent variable is the research variable that changes or varies as a result of the independent variable.

What is an independent variable for dummies?

The independent variable is the factor in an experiment that the experimenter changes. This variable is not influenced by any other factors in the experiment, but it causes change in other variables. In other words, the independent variable is the cause of change in an experiment.

How do you describe a dependent variable?

A dependent variable is a variable whose value will change depending on the value of another variable, called the independent variable. In a scientific experiment, it is the variable being tested, and therefore, it is called the dependent variable.

What's the difference between a dependent variable and independent variable?

In an experiment, there are two main variables: The independent variable: the variable that an experimenter changes or controls so that they can observe the effects on the dependent variable. The dependent variable: the variable being measured in an experiment that is “dependent” on the independent variable.

Is time an independent variable?

Time is a common independent variable, as it will not be affeced by any dependent environemental inputs. Time can be treated as a controllable constant against which changes in a system can be measured.

How do researchers manipulate the independent variable?

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.

Is an experimental design the dependent variable is?

In an experimental design, the dependent variable which can't be manipulated. Answer: Definition of the dependent variable: "Research which is undergone under the scientific accepted conditions with experimental methods."

What is experimental research in psychology quizlet?

A research method in which the investigator manipulates a variable under carefully controlled conditions and observes whether any changes occur in a second variable as a result. - Allows researchers to detect cause and effect relationships. Independent variable.

Which of the following is the independent variable in an experiment?

The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable.

What is the independent variable in the experiment above?

An independent variable is the variable that is changed in a scientific experiment. Independent variables are the variables that the experimenter changes to test their dependent variable. For example, a scientist is testing the effect of light and dark on the behavior of moths by turning a light on and off.

Which factor is the independent variable in this experiment?

The independent variable is the factor that you purposely change or control in order to see what effect it has. The variable that responds to the change in the independent variable is called the dependent variable. It depends on the independent variable. The independent variable is graphed on the x-axis.

How many independent variables are there in research?

There are often not more than one or two independent variables tested in an experiment, otherwise it is difficult to determine the influence of each upon the final results. There may be several dependent variables, because manipulating the independent variable can influence many different things.

What is another basis of experimental research?

Experimental research can be grouped into two broad categories: true experimental designs and quasi-experimental designs. Both designs require treatment manipulation, but while true experiments also require random assignment, quasi-experiments do not.

Which of the following is a definition of experimental method?

The experimental method involves the manipulation of variables to establish cause and effect relationships. The key features are controlled methods and the random allocation of participants into controlled and experimental groups.

What is experimental research design quizlet?

experimental research. carefully controlled scientific procedure that manipulates variables to determine cause and effect.
