Do we see a positive or negative relationship based on the number a new bill of cases for each: value on independent goes up and dependent goes up then there is a positive relationship, e. g. Same independent var but diff dependent var: kendall"s tau b and tau c, gamma and tau goes in both ways in determining the strength of a relationship ( 0. 3 to 1 indicates a strong relationship, etc. , e. g. the higher your edu level the less you want to spend on defense, bivariate, cannot use gamma bc we cannot make any clear comparisons.
