An investigator conducts an experiment involving the effects of three levels of a drug on memory. Participants are randomly assigned to one of three conditions. A different drug level is administered in each condition. Memory is measured 10 minutes after each subject receives the drug intravenously. The following scores are recorded. The higher the score, the better the memory. Test whether there was an effect of the drug on memory across the three conditions.
