Quick Answer: What Is A Dependent Variable In An Experiment?

What are examples of dependent variables?

The dependent variable is the variable that is being measured or tested in an experiment.

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 difference between dependent and independent variable?

The variables in a study of a cause-and-effect relationship are called the independent and dependent variables. The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect.

What type of variable is name?

Categorical Variables As the name implies, a categorical variable is made up of categories. Typically, there are a set number of categories a participant can select from, and each category is distinct from the other. Familiar types of categorical variables are variables like ethnicity or marital status.

Is age 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.

What is a 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 variable should be kept constant?

There must be an independent variable, which changes throughout the course of an experiment; a dependent variable, which is observed and measured; and a controlled variable, also known as the “constant” variable, which must remain consistent and unchanging throughout the experiment.

How many dependent variables can you have?

A well-designed experiment normally incorporate one or two independent variables, with every other possible factor eliminated, or controlled. There may be more than two dependent variables in any experiment.

What is a dependent variable in biology?

Dependent Variable. Dependent Variable: A dependent variable is what you measure in the experiment and what is affected during the experiment. … It is called dependent because it “depends” on the independent variable. In a scientific experiment, you cannot have a dependent variable without an independent variable.

Can time be a dependent variable?

If time is one of your variables, it is the independent 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).

How do you find the dependent variable?

The dependent variable is the one that depends on the value of some other number. If, say, y = x+3, then the value y can have depends on what the value of x is. Another way to put it is the dependent variable is the output value and the independent variable is the input value.

What are examples of independent and dependent variables?

Independent and Dependent Variable ExamplesIn 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.You want to compare brands of paper towels, to see which holds the most liquid.More items…•

What is the variable in an experiment?

Variables are an important part of an eye tracking experiment. A variable is anything that can change or be changed. In other words, it is any factor that can be manipulated, controlled for, or measured in an experiment.

Which is the dependent variable?

The dependent variable is the variable being tested and measured in an experiment, and is ‘dependent’ on the independent variable. An example of a dependent variable is depression symptoms, which depends on the independent variable (type of therapy).

Is income an independent variable?

For example, income is an independent variable because it causes and influences another variable consumption. In a mathematical equation or model, the independent variable is the variable whose value is given.

Is gender an independent variable?

However, gender cannot be imposed or changed by investigators, so it is always an attribute independent variable, when men and women are compared in the study (i.e., when it is an independent variable). . Since the levels of the variable are two distinct categories, it is a nominal variable.

What are the 3 types of 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 another name 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”..

What are examples of independent?

The definition of independent is someone or something that is free from the influence or control of another. An example of independent is someone who lives on their own and supports themself. “Independent.” YourDictionary.
