What is a bivariate table: the bivariate continency table is widely used it presents the same information as a. Bivariate tables without percentages: researchers condense information in another kind of bivariate table with a measure of central tendency (usually the mean) instead of percentages. It is based on a reduction in errors based on the mode and ranges between 0 (independence) and 1. 0 (perfect prediction or the strongest possible relationship) It is based on comparing pairs of variable categories and seeing whether a case has the same rank on each. It is based on a different approach than gamma and takes care of a few problems that can occur with gamma. 1. 0 to +1. 0, with 0 meaning no association.
