Document Summary
In addiion to pracice, pracice, pracice here"s a list of the topics we"ve covered so far that will appear on the second test to help you organize your studying. It is not meant to be exhausive but to give you a handy list of the main points we"ve talked about. If the sample had a lot of sampling error, we wouldn"t want to use it to make a conclusion about the populaion. 1st specify the null and 1 or more alternaives. Then decide is the sample data are convincing enough to reject the null: reject the null when you are conident any observed diferences/associaions. Staisically signiicant: the observed result is unlikely to occur if the null was true are not beter explained by chance/random factors. Example: the mean on aggression will be diferent for men and women: direcional (preferred): direcion of diference is speciied. Example: men will have higher scores on aggression than women.
