Document Summary

Replication- others should be able to do the same study as you and get similar results. Mode is the score that occurs most often. Median is the score which half the class scores above and half the class scores below. Does not reflect typical score because there could be unusually high/low scores in the data. When there are no geese in canada there are no leaves on the tree, many geese=many leaves. Smoking and cancer (associated) , heroin and marijuana. Correlational studies- a statistical measure of the extent of a relationship between two variables. Correlations vary from -1. 0 to +1. 0 positive and negative correlations. The larger the correlation the stronger the association, if there is no relationship the relationship is 0. 0. Every scientific theory must be potentially falsifiable. Based on theory, scientists form a hypothesis, stress;smoking;cancer. Assume all theory"s are false until proven otherwise. We model our peers, we learn that violence is acceptable.
