SUMMARY
This discussion clarifies the distinctions between independent, dependent, controlled, and uncontrolled variables in experimental design. The independent variable is exemplified by time, as illustrated in the scenario of placing a hand on a hotplate, where the dependent variable is the resulting pain. The relationship is direct: increased time correlates with increased pain. Controlled variables are those that can be manipulated, while uncontrolled variables are influenced by external factors.
