Control group
The group that remains the same, unchanged, does not experience the new treatment. * used for comparison *
Control

Independent variable
Factor being intentionally changed, ‘‘I’” change. ( experimental variable, or manipulated variable )
** THE DIFFERENCE **
Dependent variable

Observation
