Daniela wanted to figure out what type of liquid worked best for growing beans. She watered one with coca-cola, one with lemonade, and one with just water. After one week, she measured how high they had grown. What is the independent variable?
Answer: An independent variable is a variable that does not depend on any other variable (it is the input variable) while a dependent variable is a variable that depends on other variable (it is the output variable).
In this question the two variables are the height of the plant after a week and the type of liquid used. Since the height of the beans depend on the type of liquid, therefore the height of the beans is the dependent variable while the type of liquid is the independent variable.
