Document Summary
The m1-m2 you will observe between the groups is always 0. The m1-m2 you will observe between the groups is always different from 0. #c. observing m1-m2 of +0. 5 or -0. 5 is considered surprises, assuming null is true. #d. observing m1-m2 of +0. 1 or -0. 1 is considered surprising assuming null is true. #***the larger the n, your standard error decreases - more likely to make correct estimates. In both cases, the distributions are centered on zero and the critical t value is between 1. 96 and 2. But larger the n, the closer to 0 more m1-m2 fall that are considered surprising. In both cases, a t value of 0 is the most likley outcome, but the critical t value is around 0. 4 for n=5- and around 0. 05 for n=5000. #c/ in both cases m1-m2 will vary in exactly the same way around 0, but the type i error rate is much smaller when n=5000 than when n=50.
