Scenario: In the experiment shown, plant A received 50 mL of coke each day, plant B received 50 mL of juice, and plant C received 50 mL of water. Every
day for one week, plant growth was measured.
What is the independent variable? *

TYPE OF LIQUID SUBSTANCE RECEIVED

Explanation:

The independent variable in an experiment is the variable that the experimenter deliberately changes or manipulates in order to bring about a response in the dependent variable/measured variable.

In this experiment, the TYPE OF LIQUID was changed for each group of plant in order to see how it affects how the plants grew. Hence, the TYPE OF LIQUID is the independent variable while the dependent variable is the plant growth, which is dependent on the independent variable.

well, i believe that the answer is 2. : 3
