A researcher hypothesizes that older adults will learn most effectively with a constant background sound, as opposed to an unpredictable sound or no sound at all. She randomly divides 30 adults into three groups of 10 and calculates a mean achievement score for each group. Decide what statistical procedure would most likely be used to answer the research question. Assume all assumptions have been met for using the procedure.
