Keeping temperature the same in an experiment is what type of action?

Answer and explanation

Correct answer: Maintaining a controlled variable

Direct answer: Option B, maintaining a controlled variable. A fair experiment changes one main factor and keeps other relevant factors constant. If temperature is kept the same while another factor is tested, temperature cannot produce a hidden difference between groups. This makes any observed change more confidently linked to the independent variable. Option A is wrong because changing the independent variable means deliberately varying the test factor, not holding temperature constant. Option B is correct because temperature is being kept fixed as a controlled variable. Option C is wrong because writing a conclusion happens after examining results. Option D is wrong because a hypothesis is a testable prediction and is not removed merely by keeping a condition constant. Memory cue: controlled variables are “kept constant for a fair comparison.”
