Changes in the independent variable are independent of changes in any other variable,
The independent variable of an experiment is the variable that you change, and the dependent variable is the result of the independent variable.
An independent variable is a variable which stands independent and is unaffected by other variables. A dependent variable is a variable which is a response to the independent variable, and is usually the factor that is being tested in an experiment.
An independent variable is a factor that is manipulated or chosen by the experimenter to determine its relationship with the dependent variable. It is the variable that is changed or controlled in an experiment to study its effect on the dependent variable.
The term 'independent variable' is a noun phrase; the adjective 'independent' describes the noun 'variable'.

The dependent variable is the outcome or response that is being measured in an experiment. It is what is affected by changes in the independent variable, which is the variable being manipulated. The dependent variable is dependent on the independent variable.
The independent (or explanatory) variable is changed to test the prediction,
The independent variable is the factor that is purposely changed or manipulated by the researcher in an experiment. It is the variable that is believed to have an effect on the dependent variable, which is the outcome or response being measured. By altering the independent variable, researchers can observe how it influences the dependent variable.

The independent variable is what you are changing in the experiment to get varied results. The dependent variable is the result of what you have changed. So the dependent variable depends on the independent variable. For example, if you are experimenting with the effect of water on height of a plant, the different amounts of water that you give the plant is the independent variable. The height of the plant that you measure as the result of the water is the dependent variable.
The independent variable is the one that is manipulated or changed by the researcher. In Omar's experiment, whichever factor he is intentionally varying or testing would be considered the independent variable.
Experiment controlled
"Responding" is an adjective that describes the variable. In the context of scientific research, a responding variable is the one that is observed and measured in response to changes in the independent variable.
The term 'independent variable' is normally used to refer to the variable that you are investigating in an experiment. A common colloquial definition is 'The variable you change' which is helpful, but not always clear. AQA (A UK examination board) defines it in the following way 'The independent variable is the variable for which the values are changed or selected by the investigator' Aims of experiments are often written in the form 'How does X affect Y?' X would be the independent variable and Y the dependent variable.
