  1. APA Style Summary Statement T Tests

  2. IQ in Vermont • The mean IQ of school children in Vermont, M = 100.26, SD = 12.98, was not significantly different from 100, t(87) = 0.189, p = .85, d = .02, 95% CI [-.19, .23].

  3. Group MM mice • Reared by a house mouse in a mouse colony room. • Mice in Group MM made significantly more visits to the house mouse scented tunnel, M = 22.44, SD = 12.82, than to the rat scented tunnel, M = 7.56, SD = 5.89, t(15) = 5.639, p < .001, d = 1.49.

  4. Group MR mice • Reared by a house mouse in a rat colony room with rat scents added to their cages. • Mice in Group MR made significantly more visits to the house mouse scented tunnel, M = 22.31, SD = 10.21, than to the rat scented tunnel, M = 7.56, SD = 5.74, t(15) = 7.797, p < .001, d = 1.78.

  5. Group RR mice • Reared by a rat in a rat colony. • For the mice in Group RR, the number of visits made to the house mouse scented tunnel, M = 23.44, SD = 8.51 did not differ significantly from the number of visits made to the rat scented tunnel, M = 24.75, SD = 8.10, t(15) = 7.797, p = .54, d = .16.

  6. Weight Loss • Those who completed Program A lost significantly more weight (n = 6, M = 22.67, SD = 4.27) than did those who completed program B (n = 12, M = 13.25, SD = 4.09), t(9.71) = 4.469, p = .001, 95% CI [4.70, 14.13]. • What the most important statistic given in the statement above? • Why didn’t I compute Cohen’s d?

  7. IQ and Voting • Mean state IQ was significantly greater in states that voted for Kerry (M = 100.95, SD = 1.99, n = 20) than in those that voted for Bush (M = 99.26, SD = 2.42, n = 31), t(46.1) = 2.72, p = .009, d = .75, 95% CI [.16, 1.33].
