Specificity:
Specificity (of a medical diagnostic test for a disease) is the probability that the test will come out negative for a person without the disease.
Specificity itself is not sufficient to characterize a test. For example, a test reporting all subjects who take the test as “negative” (not having the disease) has 100% specificity, but such a “test” is useless – because it has 0% sensitivity.
Planning on taking an introductory statistics course, but not sure if you need to start at the beginning? Review the course description for each of our introductory statistics courses and estimate which best matches your level, then take the self test for that course. If you get all or almost all the questions correct, move on and take the next test.
