Statistica medica
Course syllabus
Data collection: measurement scale of the variables, coding, setting of the detection in a questionnaire.
Descriptive statistics: the distributions and their graphical representation (bar diagrams, pie charts, histograms, box-plot diagrams), the cumulated distributions and their interpretation, numerical synthesis indices (mean, median, quartiles, standard deviation, range interquartile).
Association between qualitative variables (contingency tables and indices to estimate the association strength).
Linear correlation and linear regression.
The Gaussian distribution.
Sampling schemes (simple random, stratified, clusters).
Sample distributions (averages and proportions).
Confidence intervals for averages and proportions.
Hypothesis tests for averages and proportions.
Teaching methods
Frontal lessons with exercises, and application in computer laboratory.
