Values of the chi squared distribution.
Because of the lack of symmetry of the chi square distribution separate tables are provided for the upper and lower tails of the distribution. A wald chi square test based on the difference between observed and expected weighted cell frequencies and a wald log linear chi square test based on the log odds ratios. You could use the square root of the wald statistic and produce a t test if desired.
How to use this table this table contains the critical values of the chi square distribution.

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. You could use the square root of the wald statistic and produce a t test if desired. In fact proc hplogistic uses t tests instead of the equivalent wald chi square test.
