Final Answer :
Explanation :
The placebo effect is an example of participant bias, as it involves the participant's belief and expectation impacting their response to a treatment, even if the treatment itself is inert. Experimenter bias involves the researcher's own biases consciously or unconsciously affecting the study, while random assignment and random selection biases involve errors in the sampling and assignment processes.
