Pretty much as it is in math, something that is undefined, but in Science it needs to be defined or the experiment cant continue. Your variables are basically what you measure, what you change and your control, both positive and negative (one with a 100% percent positive result and another with a 100% negative result)
The variable is the part that is changed in the experiment; the constants are the parts that stay the same.
That depends on the experiment.
A factor in a scientific experiment that is subject to change is called a variable.
A variable that stay the same during a science experiment
dependent variable
A variable is anything that can be changed in an experiment to create different results i.eTemperaturevolumemassspeedforcetime
The variable is the part that is changed in the experiment; the constants are the parts that stay the same.
The independent variable in any item that is changed during a scientific experiment. The dependent variable is the object being tested. In an experiment testing the buoyancy of wood in different solutions, the different solutions would be the independent variable.
That depends on the experiment.
In science, the dependent variable is what is being tested in the experiment. It changes as the independent variable changes, because it depends on the independent variable. The experiment can measure changes in the dependent variable through controlling the independent variable.
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.
Your variable changes in a scientific experiment.
The variable that the researcher intentionally changes in a scientific experiment is called the independent variable. This variable is manipulated by the researcher to observe its effect on the dependent variable.
Variable
The operational definition of the dependent variable in an experiment specifies how the variable will be measured or observed. It defines the specific outcome or response that is being assessed as a result of manipulating the independent variable.
A factor in a scientific experiment that is subject to change is called a variable.
In a scientific experiment, the independent variable is what is intentionally changed or manipulated by the researcher. The dependent variable is the factor that responds or changes as a result of the manipulation of the independent variable.
