A manipulated variable is also called an independent variable. It is the thing in an experiment you change or manipulate. For example, if i am doing an experiment to see how water affects the growth on plants, the amount of water is the manipulated variable.

What is the correct definition for controlled experiment?

A controlled experiment is a scientific study in which one variable is manipulated (independent variable) while all others are held constant, to observe the effects on another variable (dependent variable). The purpose is to determine causation between the variables being studied.


In a controlled experiment what does a operational definition do?

An operational definition provides a clear and specific description of how a variable will be measured or manipulated in a study. It helps ensure that the variable is defined in a way that can be consistently applied and observed, making the results more reliable and replicable.


Does A controlled experiment measures the effect of one variable?

Yes, a controlled experiment is designed to measure the effect of one specific variable while holding all other variables constant. This allows researchers to determine the direct impact of the variable of interest on the outcome being studied.


The variable which is deliberately changed in experiment?

The variable deliberately changed in an experiment is called the independent variable. This variable is manipulated by the researcher to observe its effects on the dependent variable, which is the outcome or response being measured. By controlling and changing the independent variable, researchers can determine its influence on the dependent variable.
