## What is an independent variable simple definition?

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. Usually when you are looking for a relationship between two things you are trying to find out what makes the dependent variable change the way it does.

## What is a dependent variable in the scientific method?

The dependent variable is the variable that is being measured or tested in an experiment. 1 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 independent and dependent variable in an experiment?

Independent variables (IV): These are the factors or conditions that you manipulate in an experiment. Your hypothesis is that this variable causes a direct effect on the dependent variable. Dependent variables (DV): These are the factor that you observe or measure.

What is an independent variable in statistics?

Independent variables are variables that are manipulated or are changed by researchers and whose effects are measured and compared. The independent variables are called as such because independent variables predict or forecast the values of the dependent variable in the model.

### What is a dependent variable in environmental science?

A variable is any part of the experiment that can vary or change during the experiment. The independent variable is the variable that is manipulated throughout the course of the experiment. The dependent variable, or response variable is the variable by which we measure change in response to the independent variable.

### What is a dependent variable in biology?

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.
