Study Notes
- Independent variables are variables that can be controlled and are assumed to have a direct effect on the dependent variable.
- In the example of a science student studying the growth of a specific plant, the amount of sunlight is the independent variable, while the growth of the plant is the dependent variable.
- In another example, a psychology student is studying if emotional quotient affects performance in math tests, where emotional quotient is the independent variable and performance in math tests is the dependent variable.
- A scientist studying the impact of drug A on cancer cells has drug A as the independent variable and the impact on cancer cells as the dependent variable.
- In hepatology, the use of a new antibiotic is the independent variable, while the reaction of salmonella bacteria to the antibiotic is the dependent variable.
