The given table shows the outcomes of a hypothetical Breast Cancer screening test:
Q1. Compute the sensitivity of this test and describe what this signifies?
Q2. Compute the specificity of this test and describe what this signifies?
Q3. Compute the positive predictive value and describe what this signifies?
Q4: If preclinical prevalence of the breast cancer rose in the screened population would you expect the positive predictive value to raise, drop or remain unaltered? Explain why?
Q5. If the sensitivity of this test rose in the screened population would you expect the positive predictive value to raise, drop or remain unchanged? Explain why?
