Question 5 of 5

5. Question
Please complete the sentence:

An area under the curve of 0.7:
- suggests a test is useless.
- suggests a test is almost perfect.
- is calculated using a ROC Curve, which is drawn by plotting specificity on the y and 1-sensitivity on the x.
- Can also be described as a S-Statistic of 0.7.
- there is a 70% chance of the score differentiating a patient who will have a poor outcome versus one with a good outcome.
