independent variable
The test variable (independent variable) controls the outcome variable (dependent variable).
the independent variable controls the dependent variables
An independent variable is a factor that the experimenter controls or changes in an experiment. It is manipulated to observe its effect on the dependent variable.
The manipulated independent variable is the variable that the researcher intentionally changes or controls in an experiment to observe its effect on the dependent variable. This variable is manipulated by the researcher to determine the impact it has on the outcome of the study.
the treatment that the researcher controls directly.
The independent variable is the one which the researcher controls and manipulates. On a graph this is the 'x' axis.
The variable that a scientist controls in an experiment is called the independent variable. It is manipulated or changed by the researcher to observe its effect on the dependent variable.
The condition in an experiment that can be changed is called the independent variable. This is the variable that the researcher manipulates or controls to observe its effect on the dependent variable. By changing the independent variable, researchers can determine how it influences the outcome of the experiment.
The independent variable for sugar could be the amount of sugar (in grams or teaspoons) added to a food or drink item. This variable is what the researcher manipulates or controls in an experiment to observe its effect on the outcome.
Any variable can be the independent variable. It depends partly on what the dependent variable is, partly on the relationship you are examining. For example, if looking at age and length of children's feet, foot length would be considered the dependent variable. But if looking at foot length and shoe size, then foot length would be the independent variable.
An independent variable is a part of an experiment that can change. This is the variable that the scientist manipulates or controls in order to observe its effect on the dependent variable.
