Question

the variables that remain the same (in this case the location of the plants, light input, and amount/type of soil) are called:

dependent variables

independent variables

controlled variables

Explanation:

Identify the definition of variables kept constant

The question asks for the term used to describe variables that remain the same during an experiment, such as the location of plants, light input, and soil type.

Evaluate the given options

• dependent variables: The factors being measured or observed to see how they respond to changes.
• independent variables: The factors that are intentionally changed or manipulated by the experimenter.
• controlled variables: The factors that are kept constant and unchanged throughout the experiment to ensure a fair test.

Answer:

• dependent variables
• independent variables
• controlled variables (Correct answer)
