What Is a Control Variable? Definition and Examples
A control variable is any factor that is controlled or held constant during an experiment. For this reason, it’s also known as a controlled variable or a constant variable. A single experiment may contain many control variables.
What Are Constants & Controls of a Science Project Experiment?
TL;DR: In a science experiment, the controlled or constant variable is a variable that does not change. For example, in an experiment to test the effect of different lights on plants, other factors that affect plant growth and health, such as soil quality and watering, would need to remain constant.
Control Variables | What Are They & Why Do They Matter? - Scribbr
A control variable is anything that is held constant or limited in a research study. It’s a variable that is not of interest to the study’s objectives, but is controlled because it could influence the outcomes.
Definitions of Control, Constant, Independent and Dependent ...
The factors that can change value during an experiment or between experiments, such as water temperature, are calledscientific variables, while those that stay the same, such as acceleration due to gravity at a certain location, are called constants.
What Is an Experimental Constant? - ThoughtCo
Learn what an experimentalconstant is and get examples of two main types of constants you may encounter in experiments.

Why are most factors held constant in a scientific experiment? Most factors are held constant in a scientific experiment because you can onlychangeone factor in an experiment so if you notice something, you'll know what caused it.

A _____ is a carefully regulated procedure in which one or more variables believed to influence the behavior being studied are manipulated while all other variables are heldconstant.
Independent and Dependent Variables Examples
The independent variable is the factor the researcher changes or controls in an experiment. It is called independent because it does not depend on any other variable. The independent variable may be called the “controlled variable” because it is the one that is changed or controlled.
Chp 1 bio Flashcards - Quizlet
To investigate a hypothesis, a researcher often runs a test multiple times with one factor changing and, ideally, all other factorsheldconstant. What is a variable? Variables are factors that change in an experiment.
What are constants in a scientific experiment? - Sage-Advices
To ensure the measured effect is not influenced by external factors, other variables must be held constant. These variables that are made to remain constant during an experiment are referred to as the control variables.
