# What are the definitions of independent and dependent variables?

## What are the definitions of 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 is the difference between dependent and independent variables give the definitions and an example?

A dependent variable depends on an independent variable, while an independent variable depends on external manipulation. For example, when measuring how the speed of a car will affect the time it will take to reach a certain place, the time taken (dependent variable) depends on the speed (independent variable).

What is a simple definition of 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 best definition for the dependent variable?

Definition of dependent variable : a mathematical variable whose value is determined by that of one or more other variables in a function.

What is the difference between an independent and a dependent variable quizlet?

Terms in this set (2) An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.

What is the difference between independent and dependent and controlled variables?

Independent variable – the variable that is altered during a scientific experiment. Dependent variable – the variable being tested or measured during a scientific experiment. Controlled variable – a variable that is kept the same during a scientific experiment.

## How many independent variables are there?

There are often not more than one or two independent variables tested in an experiment, otherwise it is difficult to determine the influence of each upon the final results. There may be several dependent variables, because manipulating the independent variable can influence many different things.

What is the difference between independent and dependent variable in spreadsheets?

Think of the independent variable as the input and the dependent variable as the output.

What are independent and dependent variables in psychology quizlet?

Independent variable. The variable that the researcher manipulates or changes (in an exam you should give both conditions). Dependent variable. The variable that research measures. You just studied 2 terms!

### What is the difference between independent and dependent events quizlet?

Two events are independent when the occurrence of one event does not affect the probability of the occurrence of the other event. Two events are dependent when the occurrence of one event affects the probability of the occurrence of the other event.

Why is it called an independent variable?

Independent variables are variables that are manipulated or are changed by researchers and whose effects are measured and compared. The other name for independent variables is Predictor(s).

How do you identify the independent and dependent variables in science?

If the independent variable is changed, then an effect will be observed in the dependent variable. Both independent and dependent variables may change during the duration of the experiment. However, the experimenter is in control of changing the independent variable but not the dependent variable.
