# Often asked: What Is The Meaning Of Independent Variables In Science?

## 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 is a independent variable in Science example?

Time as an Example of an Independent Variable

Question Independent Variable (What I change) Controlled Variables (What I keep the same)
How fast does a candle burn? Time measured, in minutes Use same type of candle for every test Wind—make sure there is none

## What does independent and dependent variable mean in science?

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. Its value depends on changes in the independent variable.

## What does an independent variable do?

An independent variable is a variable that represents a quantity that is being manipulated in an experiment. x is often the variable used to represent the independent variable in an equation.

## What are 3 types of variables?

There are three main variables: independent variable, dependent variable and controlled variables.

## How do you identify an independent variable?

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 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. Free from the influence, guidance, or control of another or others; self-reliant.

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.

## How do you distinguish between dependent and independent variables?

A dependent variable is a variable whose variations depend on another variable —usually the independent variable. An Independent variable is a variable whose variations do not depend on another variable but the researcher experimenting.

## What is control variable in your own words?

Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.

## Where do you plot the independent variable?

The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line).

## Which is the dependent variable?

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.

## How do you manipulate independent variables?

Manipulation of 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.

## What is an 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.
