The New Horizons Alcohol and Drug Abuse Center has begun to collect data on client satisfaction. In addition to offering individual counseling, the center has optional group-activities programs for its clients. The director of the center would like to know if clients who have participated in the group-activities programs are more satisfied with their treatment than those who have not participated in them. The director gathers data on 100 clients. Each client is classified as having participated in group programs (coded 1) or not (coded 0). Data on client satisfaction are taken from an exit survey that asked clients to rate their treatment as satisfactory (coded 1), neutral (coded 2), or unsatisfactory (coded 3). What can the director conclude about the link between participation in group programs and client satisfaction from these data?
