The results of this study suggest that there are similar bond strengths between the 1 and 2 bottle self etch. Wald chi square test proc surveyfreq provides two wald chi square tests for independence of the row and column variables in a two way table. Together with the lagrange multiplier and the likelihood ratio test the wald test is one of three classical approaches to hypothesis testing.
