An Investigator Conducts an Experiment Involving the Effects of Three

question 111

Multiple Choice

An investigator conducts an experiment involving the effects of three levels of a drug on memory. Subjects 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. The following scores are recorded. The higher the score, the better the memory. An investigator conducts an experiment involving the effects of three levels of a drug on memory.
