Participants (N=12) in a study were randomly assigned to one of two types of therapy - either talk therapy or drug therapy (n = 6 per condition). Mood scores were analyzed at two time points for all clients: 4 weeks and 12 weeks into the start of the therapy. Mood scores are presented in the table below, with higher scores indicating improved / more positive moods. Use the data to answer the questions in this set.

	Talk		Drug
	4 weeks	12 weeks		4 weeks	12 weeks
P1	7	9	P7	4	7
P2	5	7	P8	5	9
P3	4	5	P9	4	5
P4	6	6	P10	3	6
P5	7	8	P11	2	5
P6	7	7	P12	4	6
