the dependent varible
A statistical technique used to eliminate variance in dependent variables caused by extraneous sources. In evaluation research, statistical controls are often used to control for possible variation due to selection bias by adjusting data for program and control group on relevant characteristics.
Any variable can be the independent variable. It depends partly on what the dependent variable is, partly on the relationship you are examining. For example, if looking at age and length of children's feet, foot length would be considered the dependent variable. But if looking at foot length and shoe size, then foot length would be the independent variable.
Positive controls : an experimental treatment that will give the desired result Negative controls: An experimental treatment that will NOT give the dersired result.

the dependent varible
The independent variable is the one which the researcher controls and manipulates. On a graph this is the 'x' axis.
the treatment that the researcher controls directly.

According to psychologists, the behaviorist perspective is the belief that people learn from environment because their environment controls their actions. For example, individuals who are in a good environment will behave positively than individuals who are in a negative environment.
In some cases, the direction of evolution is intentionally controlled by humans. We call this artificial selection, or breeding - as in the breeding of cattle. In all other cases, nobody controls the direction of evolution.

Physical Controls
Physical Controls
There are three basic categories of controls. Physical controls may take the form of barriers and guards or signs to warn individuals and units that a hazard exists.
