TEACHING

Teaching to medical undergraduates

§ Sources of data (health information system, patient records, government reports)

§ Measures of morbidity and mortality (infant mortality rate, maternal mortality ratio, age specific death rate, age standardized death rate) and incidence and prevalence rates.

§ Demography and fertility (various fertility rates, demographic cycle, population pyramid)

§ Graph and diagram (bar diagram, pie diagram, line diagram, other charts)

§ Statistical distributions (histogram, polygon, normal distribution, skewed distribution)

§ Regression and correlations (linear regression, product moment correlation coefficient, causal relationship)

§ Tests of significance (Chi-square, student’s t test and elements of ANOVA F test)

§ Confidence intervals for means, proportion, difference in means and difference in proportions

Teaching to medical postgraduates

· Medical uncertainities (epistemic and aleatory)

· Designs to control the impact of uncertainities (observational studies, experiments and clinical trials)

· Adequacy of samples (method of sampling and size of samples)

· Collation of data

· Assessment of health and disease (normal/abnormal levels, morbidity, mortality and duration of survival)

· Degree of uncertainities (sensitivity/specificity, predictivities and relative risk)

· Statistical significance (P-value, power, Chi-square, t, F, repeated measures, nonparametrics—medical significance)

· Medical relationships (Correlation and cause-effect, linear regression—simple, multiple)
