d) Confounding variable

Answer 1

The correct answer is Placebo effect, which refers to the phenomenon where an inert substance or condition is assumed to be the active agent, causing experimental results due to expectations alone. It helps control for both experimenter and participant expectations to ensure unbiased results.

Step-by-step explanation:

The correct answer is a) Placebo effect. The placebo effect refers to the phenomenon where an inert substance or condition is assumed to be the active agent, causing experimental results due to expectations alone. It occurs when people's expectations or beliefs influence their experience in a given situation. This is an important consideration in studies as it helps control for both experimenter and participant expectations, ensuring that any effects observed are not due to biases or expectations.
