Question
A new screening test for thyroid cancer was administered to 1,000 adult volunteers at a large medical center complex in Europe. The results showed that 152 out of 160 diagnosed cases of thyroid cancer were correctly identified by the screening test. Also, of the 840 individuals without thyroid cancer, the screening test correctly identified 714. Base on this information, calculate the test's: 1. Sensitivity 2. Specificity 3. Positive predictive value 4. Negative Predictive Value 5. Accuracy 6. Prevalence rate. Please help with 4,5,6. I have attached 1,2,3.
Test positive Test negative Total 1. Sensitivity 152/160 = 0.95 =0.95 2. Specificity 714/840 = 0.85 =0.85 = With thyroid Cancer Without th. Cancer 152 (a) 126 (b) 3. Positive predictive values 152/278 0.546763 = 0.546763 4. 8 (c) 160 (a+c) 714 (d) 840 (b+d) Total 152+126=278 8+714=722 1000
