Document Summary

Didn"t decide ahead of time make small amount of comparisons. If you cant figure out what tests to do ahead of time then you cant discriminate which t tests you do during post hoc. You can however before you gather your data which t test you will compare. This choice will not be made for statistical reasons. It will be made due to prior studies or common knowledge which will allow interesting questions to be answered. This will decrease the amount of tests and increase power. The count and rhyme group can be compared to group 3,4&5. In assignment 4 you need to find what the interesting questions are. Explain a reason for every t test you conduct. A contrast is a sum of means from experiments each multiplied by a coefficient.
