Respuesta :
Dependent variables are those that need a stimulus to present themselves. The independent variables are those that do not need a stimulus to present themselves and the control variables are the elements that remain unchanged throughout the experiment.
Importance of variables
- They present the relationship between the elements of the experiment.
- Allow hypotheses to be tested.
- Allows comparisons between experimental treatments.
- They encourage the evaluation of experimental data.
To increase the understanding of these variables, we can use as an example an experiment that seeks to evaluate the influence of root growth of transgenic corn with water stress. In this experiment, five plants of transgenic corn will suffer different levels of water stress, while one plant of the same corn will not suffer this stress and will be watered normally.
According to this, root growth is a variable that needs a stimulus to present itself, so this is the dependent variable. Water stress does not need any stimulus, being the independent variable. Finally, the corn plant that will not suffer any type of stress will remain unchanged throughout the experiment, being the control variable.
