# What is an independent variable in quantitative research?

## What is an independent variable in quantitative research?

Independent variables (IV) are those that are suspected of being the cause in a causal relationship. If you are asking a cause and effect question, your IV will be the variable (or variables if more than one) that you suspect causes the effect.

What are dependent and independent variables in quantitative 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 is an example of 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.

Is month an independent variable?

The months do not change as a function of mass. That would be like saying, “When Chloe is 75kg it must be the 4th month.” One variable changes in relation to another. The independent variable is the one you either control or you already know how it changes.

## 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).

Is year an independent variable?

Rainfall depends on time of year, but time of year does not depend on rainfall. Therefore, rainfall is the dependent variable and time of year is the independent variable.

### Is height an independent variable?

the average height of adults might give you a graph as shown below. The independent variable is average height. The dependent variable is weight. For example, height might be an independent variable in the context stated above but a dependent variable in a study on the effect of nutrition on growth rates.

What are dependent and independent variables in research?

In an experiment, the independent variable is the variable that is varied or manipulated by the researcher, and the dependent variable is the response that is measured. An independent variable is the presumed cause, whereas the dependent variable is the presumed effect.

## How do you determine independent and dependent variables?

Independent and dependent variables always go on the same places in a graph. This makes it easy for you to quickly see which variable is independent and which is dependent when looking at a graph or chart. The independent variable always goes on the x-axis, or the horizontal axis. The dependent variable goes on the y-axis, or vertical axis.

What is dependent variable in research studies?

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 dependent variable in research methods?

A dependent variable (DV) is a measurement. In well-designed experimental research, the DV is the measure of the effect of the independent variable (IV) on participants’ responses.
