7 Bob’s DataAlice’s Data C1 Standard Deviation: 2.05 T1 Standard Deviation: 1.41 C2 Standard Deviation: 0.82 T2 Standard Deviation: 0.82 Average Standard Deviation: 1.73 Average Standard Deviation: 0.82

8 Bob’s DataAlice’s Data Average Standard Deviation: 1.73 Average Standard Deviation: / 1.73 =.58 Effect Size =.58 1 / 0.82 = 1.22 Effect Size = 1.22 Effect Size > 1 = GOOD!

11 p = probability that your difference was due to random factors!

12 Bob’s DataAlice’s Data p = >.05 (22% probability that Bob’s results are due to chance) p = <.05 (1% probability that Alice’s results are due to chance)

13 Thank You & Happy Analyses!
