Learning outcomes
The main objective of this course is to provide basic knowledge on the following items:
-descriptive statistics
-elements of probability
-rates and methods of standardization
-computation of basic statistics using Excel
Course contents
The course contents are based on four main topics:
Part 1 - Descriptive Statistics (12h)
Types of data, qualitative and quantitative variables, discrete and continuous variables
Data presentation: frequency tables (frequency counts, relative frequencies) and graphical representations (e.g. pie charts, bar charts, histograms, scatter plot, time series, cartograms)
Measures of central tendency (mean, median, mode and percentiles)
Measures of variability (range, interquartile range, deviation, variance, standard deviation, variation coefficient)
Skewness and kurtosis
Part 2 - Relationships between two variables (4h)
Contingency Tables
Joint frequencies and joint relative frequencies
Conditional and marginal distributions
Relationships between two variables
Chi-squared statistics
Tschuprow’s T
Part 3 - Elements of Probability (4h)
Introduction to probability
Remarks on the concepts of probability
Definition of simple events and sample space
Operations on events (Venn diagrams)
Axioms of probability (Kolmogorov)
Rules of the probability (additive, multiplicative)
Conditional probability
Bayes’ theorem
Part 4 - Rates and Rate Standardization (4h)
Crude rates
Specific rates
Standardization of rates (direct and indirect methods)
Lab (12h)
Introduction to Microsoft Excel
Computer exercises using Excel
Readings/Bibliography

Teaching methods
Lectures
Classroom exercises
Computer exercises (using Excel)
To attend lab room activities, students have to take an online class about “formazione sulla sicurezza nei luoghi di studio” (module 1 and 2).
Assessment methods
Medical Statistics
The aim is to evaluate whether students have learnt the basic tools of the subject, including the use of Excel. In particular, students should achieve the following learning outcomes:
- knowledge of the basic tools of Statistics
- use of those tools for data analysis
- interpretation of the findings
The exam will consist of: 1) exercises to be solved using Excel; and 2) multiple choice test with only one correct option. The scores will be the following: +1 for correct answers, -0.25 for incorrect answers, 0 for unanswered questions.
The exam will take place in the computer room of Palazzo dal Pero, Imola. Duration: 1 hour.
Students are allowed to use calculators. Notes and formulary are not permitted.
The evaluation of the exam is expressed as a mark out of 30. The minimum passing grade is 18/30, the maximum 30/30 cum laude.
Students must sign up using AlmaEsami. Late registrations are not admitted.
“Statistics and Epidemiology”
The final score will be calculated as weighted average of the individual marks of the following exams:
- Medical Statistics (3 CFU)
- Epidemiology – Vaccination Strategies (3 CFU)
To be noted that Prof. Gori (lecturer in Epidemiology – Vaccination Strategies) will be in charge of the recording of the final score.
Teaching tools
Whiteboard, PC, video projector, computer lab.
Students with disabilities or Specific Learning Disabilities (SLD) are invited to inform the teacher of their needs in order to adopt appropriate measures or tools.
