Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the independent variable in an experiment?
A
the variable the experimenter has control over
B
the data the experimenter is collecting
C
factors that do not change over the course of the experiment
D
None of the above
Explanation: 

Detailed explanation-1: -Variables are given a special name that only applies to experimental investigations. 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.

Detailed explanation-2: -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.

Detailed explanation-3: -An independent variable is manipulated by the experimenter. Any changes made are predictable. The dependent variable reacts to changes made to the independent variable. Its changes are not controlled by the experimenter and can be hard to predict.

Detailed explanation-4: -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.

Detailed explanation-5: -Hence, it could be concluded that in experimental method, the variable which is under the control of experiment is known as ‘independent variable’. It is a variable which is controlled by the experimenter. It is a variable which is measured by the experimenter.
