VARIABLES
Designing the procedure of an investigation should look into fair testing.
The variables of the study should be determined to limit any factor that may affect the result of the experiment. A variable is any factor present in the experiment. The three basic variables are the independent, dependent, and control variables.
The independent variable
is the factor that affects the result of the study.
The dependent variable
is the result of the study.
The control variable
is the factor kept constant or controlled throughout the experiment, so that it will not intervene or affect the result of the experiment.
To make sure that the experiment shows a fair test, one independent variable is tested at a time and the rest of the variables are controlled.
