WebAs with sensitivity I currently have no idea what the meaning of a weighted average specificity would be. And trying to think what specificity for yes means is making my head spin. I understand specificity to be calculated as follows: T r u e N e g T r u e N e g + F a l s e P o s = 228 228 + 7 = 228 235 = 0.970. WebSensitivity and specificity are two of them. In short: at a sensitivity of 100% everyone who is ill is correctly identified as being ill. At a specificity of 100% no one will get a false positive test result. Tests that score 100% in both areas are actually few and far between.
