## What is 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 an independent variable in science?

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 are the characteristics of dependent variable?

The dependent variable responds to the independent variable. 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. Example: You are interested in how stress affects heart rate in humans.

## What is dependent and independent variable in statistics?

Dependent and Independent Variables An independent variable, sometimes called an experimental or predictor variable, is a variable that is being manipulated in an experiment in order to observe the effect on a dependent variable, sometimes called an outcome variable.

## What is another name for dependent variable?

The other name for the dependent variable is the Predicted variable(s). The dependent variables are named as such because they are the values that are predicted or assumed by the predictor / independent variables.

## Is income a dependent or independent variable?

Now there are three variables: your salary and your investment income are independent variables and the amount you spend is the dependent variable. Definition: A function is a mathematical relationship in which the values of a single dependent variable are determined by the values of one or more independent variables.

## What is the independent variable in qualitative research?

In a research study, independent variables are antecedent conditions that are presumed to affect a dependent variable. They are either manipulated by the researcher or are observed by the researcher so that their values can be related to that of the dependent variable.

## Is there independent and dependent variables in qualitative research?

You DON’T use variables in qualitative research, and there is NO clearcut way to determine so called independent and dependent variables.

## 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.

## How do you measure dependent variable in research?

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.

## What is an operational dependent variable?

An operational definition of a dependent variable can be qualitative. That is, your measurement of the dependent variable can simply be an observation of whether a change occurs as a result of a change in the independent vari- able. This type of operational definition can be thought of as a “yes or no” measurement.

## What is a research variable?

A research variable (also called a study variable) is an informal term that means any variable used in research that has some kind of cause and effect relationship. For example, this Study Variable worksheet asks the researcher to “Name the study variables and label each as either independent or dependent.”
