Exam 14: Factorial Anova: Additional Designs

An experimental neuropsychologist wishes to determine whether a new drug (X-9) enhances the growth of new, functional brain tissue after maximal brain growth has already been attained after a period of 1 month and 6 months. Five rats were run in a series of three different mazes. All of the mazes were judged to be of equal difficulty. The time in seconds to solve each maze is recorded for each rat across its three mazes. X-9 was given 2 weeks before testing. A prior study statistically demonstrated that rats not given X-9 did not improve their times. Is there any evidence X-9 works? 1 Month 6 Months Trial 1 Trial 2 Trial 3 Trial 1 Trial 2 Trial 3 Rat 1 10 12 5 4 5 4 Rat 2 15 14 8 6 5 4 Rat 3 14 14 7 6 7 7 Rat 4 9 10 5 7 8 8 Rat 5 12 11 4 7 6 7 -The SST is

A researcher wishes to determine whether the controversial healing touch therapy is successful when the patients are unaware that the therapist is using "healing touch." Twenty patients with acute back pain are randomly assigned to either an unaware condition, where the patients sleep through the sessions, or an aware condition, where they are awake. The patients then receive three sessions each of healing touch therapy. After each session, the patients are asked to rate their pain on a 1 to 10 scale, where 1 = no pain and 10 = maximum pain. $\quad$ Unaware Sessions $\quad$$\quad$$\quad$$\quad$$\quad$ Aware Sessions 1 2 3 1 2 3 Patient 1 8 8 9 Patient 11 5 3 2 Patient 2 7 7 8 Patient 12 6 7 4 Patient 3 5 4 3 Patient 13 5 3 2 Patient 4 4 6 4 Patient 14 4 3 1 Patient 5 7 9 6 Patient 15 4 2 1 Patient 6 5 5 4 Patient 16 3 1 1 Patient 7 8 9 10 Patient 17 3 3 3 Patient 8 10 9 9 Patient 18 4 3 2 Patient 9 9 8 9 Patient 19 2 4 2 Patient 10 8 9 9 Patient 20 2 2 1 -The interaction was
