Answer:
Independent variable: ALTITUDE
dependent variable: GROWTH OF PLANTS
Confounding variable: STOREYS OF THE BUILDING
Explanation:
In an experiment, the basic components i.e primary variables that an experiment should contain, are the independent and dependent variables.
- The independent variable is the variable that is changed or manipulated in an experiment. In this experiment, the ALTITUDE of the plant is the independent variable.
- The dependent variable is the variable that responds to changes to the independent variable. It is the variable measured in an experiment. In this case, the dependent variable is the GROWTH OF THE PLANTS.
- The confounding variable is a variable that has an extra influence on the outcome of the experiment. In other words, the confounding variable has an impact on the dependent variable. In this case, the confounding variable is the STOREYS OF THE BUILDING.
