INTRODUCTION The role of Statistics in Health Professions. DESCRIPTIVE STATISTICS Different measurement scales – Statistical variables and their presentation through frequency distributions: one-entry or double-entry tables – Measures of central tendency: mean (arithmetic, geometric, weighted), median, mode, percentiles – Measures of dispersion: range, interquartile range, sum of squares, variance (mean square), standard deviation, variation coefficient. PROBABILITY Classic, frequentist, subjective interpretations of probability – Sum and product rules of probability – Independent and dependent events and conditional probability – Sensitivity, specificity, positive and negative predictive value of a diagnostic test – ROC curves – Bayes theorem and its application to differential diagnosis – Random variables – Theoretical probability distributions: normal distribution. SAMPLING Populations and samples - Common sampling designs – Sampling distribution of an estimator (sample mean). STATISTICAL INFERENCE Point and interval estimates: confidence interval – Logical structure of hypothesis testing: null and alternative hypotheses; acceptance and rejection regions; type I and type II error; power of a statistical test – Choice of statistical test. EPIDEMIOLOGY Measures of disease frequency: prevalence, incidence – Measures of association: risk difference, relative risk, etiologic fraction, odds ratio – Study design: cross-sectional, cohort and case-control studies.
