Hypotheses, dependent and independent variables form a set of tools that help us to create theories about natural phenomena.
The process for investigating a particular phenomenon in nature usually involves three levels. In the first level, observation of facts, phenomena, behaviors and activities takes place; at the second level, we have the hypotheses and finally, at the third level, theories, valid and sustainable hypotheses (those that have been tested) arise.
Independent Variable:
these variables influence, affect or determine other variables.
it is a determining factor, condition or cause for a given result, effect or consequence.
it is the factor manipulated by the researcher in order to determine the relationship of the factor with the observed phenomenon, to see what influence it has on a possible result.

Technical obsolescence<span> is the point at which an item is not in fact
better than other comparative items. For instance, you may purchase the most
