# What is the variable that is purposely changed in an experiment?

## What is the variable that is purposely changed in an experiment?

The variable that is purposely changed to test a hypothesis is called the manipulated variable (also called the independent variable). The factor that may change in response to the manipulated variable is called the responding variable (also called the dependent variable).

What is a variable that is tested and changed?

Scientists use an experiment to search for cause and effect. The independent variable is the one that is changed by the scientist. To insure a fair test, a good experiment has only ONE independent variable. As the scientist changes the independent variable, he or she records the data that they collect.

### What type of variable is purposely changed to test a hypothesis?

Manipulated variable
Manipulated variable: The factor in an experiment that is deliberately changed to test the hypothesis. Controlled variable: any factor during an experiment that a scientist purposely keeps the same.

What is defined as the variable in a controlled experiment that is purposely changed or manipulated quizlet?

Terms in this set (12) Independent variable. factor in an experiment that a scientist purposely changes; also known as a manipulated variable.

## Which variable is the effect of changing one of the variables?

One is called the dependent variable and the other the independent variable. The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable.

What do you call the factor that is purposely changed in an experiment between subject groups?

Independent variable. factor in an experiment that a scientist purposely changes; also known as a manipulated variable. dependent variable. factor in an experiment that a scientist wants to observe, which may change because of the manipulated variable; also known as a responding variable.

### Which is an example of a variable that can be changed?

factors in an experiment that can be changed, example would be: changing the temperature, the amount of light present, time, concentration of solutions used etcetera. What is the difference between the independent and the dependent variables in an experiment? The independent variable is the variable that is deliberately changed by the scientist.

What is the purpose of changing an independent variable?

Dependent Variable. The purpose of changing an independent variable is to decide how the changes affect something else, which is called the dependent variable. In other words, changes in the independent variable may cause the dependent variable to change.

## How are variables changed in a controlled experiment?

controlled experiment “only one variable is changed at a time. All other variables should be unchanged or “controlled”. If several variables were changed at the same time, the scientist would not know which variable was responsible for the observed results.”

What are the three types of a variable?

A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist.
