Measured in an experiment are the 'signals' sent by a 'system'. Most scientist call this 'Data'.


In any experimental study there is 'The System' and 'The Surroundings'. 'The System' is the 'object of interest' being studied and 'The Surroundings' is everything else. In 'The Surroundings' is YOU (The Observer) investigating the object of interest. In doing so, YOU are receiving 'signals' sent by 'The System' and YOU (The Observer) are recording these signals in the form of 'Data' which are the 'Factors' you are asking about. 'Data' is the 'language' of the universe which comes to you in the form of measurable quantities that you the observer collects, analyzes and interprets in terms of the behavior of The System (object of interest) being studied. The interpretation of the 'Data Factors' are the 'Conclusions' that give insight into the 'object of interest' that is the focal point of an experimental study.

Albert Einstein once said, "In order to understand the secrets of the universe, one must first learn its language".

The dependent variable, which is graphed on the y-axis.


The dependent variable depends on the independent variable. The independent variable is independent of all other factors in the experiment, and is graphed on the x-axis.


Sarah performed an experiment in which different pressures were exerted on a syringe that contained a gas. She measured the volume in response to the different pressures.

The independent variable was the pressure, and the dependent variable was the volume because the volume depended on the pressure, and it was the variable that was measured in response to the pressure.
