You have two samples of adults preparing for barium enema tests the next day. The control group consumes 2 oz of milk of magnesia with a mean average of 120 ml and a standard deviation of 10 ml of water. The second group is advised to consume more water with their milk of magnesia, and they average 124 ml with a standard deviation of 12 ml of water. Calculate the effect size in this experiment. Is it small, moderate, or large by Grove’s standards?
