Independant variable
Defintions
scientific 1. noun
a. The variable that the scientist changes during an experiment[1]
b. a variable that is changed or controlled in a scientific experiment[2]
c. what is varied during an experiment[3]
d. The variable that is stable and unaffected by the other variables you are trying to measure. It refers to the condition of an experiment that is systematically manipulated by the investigator. It is the presumed cause.[4]
Independant variable in Context
"Independent Variables – These are the variables that YOU will change in your experiment.
You should try to have only one independent variable at a time in your tests so you know for
certain that the results you are seeing are caused by the one change you made." Army Educational Outreach Program:Variables, Constants, and Controls[5]
"Independent Variables: These are felt to cause some change in the dependent variables. They are manipulated by the researcher." Experimental and Correlational Research[6]
"There can only one independent variable and one dependent variable in an experiment . Everything else that can impact the experiment must be kept constant or controlled. These are known as “controls”." University of Texas Health; San Antonio [7]
"The variable(s) that you alter intentionally in function of the experiment are called independent variables, while the variables that do not change by intended direct action are called dependent variables." The Scientific Method/Independent and Dependent Variables[8]
