Observe the following curves. What will happen to Sensitivity and Specificity if curve changes from Blue to Red?: (A) Both Sensitivity & Specificity increase, (B) Both Sensitivity & Specificity decrease, (C) Sensitivity increase & Specificity decrease, (D) Sensitivity decrease & Specificity increase
Answer is A. (a) Both Sensitivity & Specificity increase* If Blue color curve changes to Red color curve (see Photograph in Question), then- FN will reduce, Sensitivity will increase (see Photograph given in Answer)- FP will reduce, Specificity will increase (see Photograph given in Answer).
