Statistical hypotheses Null hypothesis (H0): No difference or relation exists; e.g. Treatment A is not better than Treatment B Alternative or research hypothesis (H1): Some difference or relation exists, e.g. Treatment A is better than Treatment B Statistical errors Type I error (alpha): False positive (Falsely rejecting Null-hypothesis; i.e. null…

Let’s unveil the mathematics behind the relation between: Prevalence (Pre-test probability) Predictive value (Post-test probability) Sensitivity Specificity SYMBOLS: Total screened population = nPrevalence = PSensitivity = SnSpecificity = SpTrue positive = TPTrue negative = TNFalse positive = FPFalse negative = FNWith disease = D+Without disease = D-Positive predictive value =…

A. Parallel testing 2 screening tests are applied simultaneously: So, this test will have: B. Series testing After the 1st screening test is conducted, those who test positive are only tested with the 2nd screening test: So, this test will have: Formulae for combined specificity and sensitivity A. Parallel testing:…
