So you have 14 clinics, and in each clinic you have counts for 2 states (defect/nondefect).

A global test of whether the distribution between defect/nondefect is the same for all

clinic populations could be a Chi² test for the 14 x 2 table. You could use a statistical

online calculator for this, or any statistical software.

If you have the Chi² result that globally the distribution differs between clinics, then you

should preferably use an online calculator or a software which calculates the *standardized *

cell residuals within the Chi² procedure*.* These residuals indicate the cells of your table

in which frequencies markedly differ from what would be expected if the distribution

was uniform (a marked diffrence is often assumed if the standardized residual is > 1.96

or < 1.96).

With kind regards
