Document Summary

Only the strenght of the relationshop between 2 variables. Does not imply causation increases in one variable causes the other to increase or decrease. For negative, it would slope down from y to x. No correlation would be all over the place with no direction. Used for ordinal data or skewed continuous data. Range 1 to + 1 indicating perfect agreement between ranks rather than values. Also used for variables that do not have a linear relationship. Has to do with incidence (# of new cases during a time of evaluation divided by pop @ risk) Determines the risk of a disease state development in pats exposed to a factor vs those not exposed. Make results look more dramatic as opposed to using ari. If the incidence is the same, then that means the exposure had no effect. Used in case-control studies to determine the risk of exposure to a factor on development of a certain characteristic or.
