Independent Variable (IV)
The variable that is changed by experimenter.
The independent variable is changed by the experimenter so that the results can be compared to the control, which does not change. Any differences between the control and experimental group are due to the independent variable. cw: As written, you don't.
The independent variable.
The independent variable.
The dependent variable which is measured. or Manipulated variable which is changed by the experimenter.
controlled variable
controlled variable (A+)
It can be but it is equally possible that the experimenter has absolutely no control over the independent variable. For example, in studying the grades of a class in a school, the pupils' gender may be an independent variable of interest. But the experimenter cannot control that variable.
In an experiment the independent is the stimulus, the thing controlled or applied by the experimenter. The dependent variable is the response, the reaction to the independent variable.
The Variable is the one factor that differs in a controlled experiment.
The experimenter decides on a set of values for the independent variable, then measures the value of the dependent variable for each one.
It can be but not always. The experimenter may just have to take the independent variable as it happens.
Independent variable is what you, the experimenter, change or enacts in order to do your experiment
The variable that is changed by experimenter.
Independent Variable (IV)
A fingerprint pattern is not a controlled variable in a scientific experiment. Controlled variables are factors that are intentionally kept constant to ensure that the effects of the independent variable can be accurately measured. Fingerprint patterns are unique to individuals and cannot be controlled or manipulated in a controlled experiment.
