# Quick Answer: What Is An Example Of An Independent Variable?

## What are some examples of independent and dependent variables?

Here are some other examples of dependent and independent variables in scientific experiments: A scientist studies the impact of a drug on cancer.

The independent variables are the administration of the drug – the dosage and the timing.

The dependent variable is the impact the drug has on cancer..

## What are examples of dependent variables?

Dependent Variable in Experiments. 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 psychology example?

The independent variable is the variable that is controlled and 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. The dependent variable is the variable that is measured by the experimenter.

## What are the 3 types of variables?

An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist.

## How do you identify an independent variable?

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 the difference between dependent and independent variable?

The independent variable is the variable the experimenter changes or controls 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 independent variable in algebra?

An independent variable is a variable that represents a quantity that is being manipulated in an experiment. A dependent variable represents a quantity whose value depends on those manipulations.

## What is an example of a independent variable in math?

Mathwords: Independent Variable. A variable in an equation that may have its value freely chosen without considering values of any other variable. For equations such as y = 3x – 2, the independent variable is x. The variable y is not independent since it depends on the number chosen for x.

## Is time an independent variable?

The independent variable is always displayed on the x-axis of a graph, while the dependent variable appears on the y-axis. Time is a common independent variable, as it will not be affeced by any dependent environemental inputs.

## 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 levels of an independent variable?

If an experiment compares an experimental treatment with a control treatment, then the independent variable (type of treatment) has two levels: experimental and control. … In general, the number of levels of an independent variable is the number of experimental conditions.

## 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 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.
