The situation is this Each data point has two or more different quantities associated with it and we want to know whether knowledge of one quantity gives us any demonstrable advantage in predicting the value of another quantity. In many cases one variable will be an independent or control variable and another will be a dependent or measured variable. Then we want to know if the latter variable is in fact dependent on or associated with the former variable. If it is we want to have some quantitative measure of the strength of the association. One often hears this loosely stated as the question of whether two variables are correlated or uncorrelated but we will reserve those terms for a particular kind of association linear or at least monotonic as discussed in and . Notice that as in previous sections the different concepts of significance and strength appear The association between two distributions may be very significant even if that association is weak if the quantity of data is large enough. It is useful to distinguish among some different kinds of variables with different categories forming a
