3) Two plants are grown using the same light and pots. One plant is given water that has been microwaved and the other plant is given regular tap water. Their height is measured after 2 weeks.
What are the independent and dependent variables?

Independent variable- nature of irrigation water

Dependent variable- height of the plants

Explanation:

In every study, there must be an independent and a dependent variable. The dependent variable changes its value as the value of the independent variable changes.

When the nature of irrigation water is manipulated, the height of the plant changes accordingly. This implies that the nature of irrigation water (microwaved or tap water) is the independent variable while the height of the plant (the response) is the dependent variable.
