Physics and statistics

A.Y. 2021/2022
Overall hours
FIS/07 ING-INF/07 MED/01
Learning objectives
- Acquisition of the physical knowledge necessary for the understanding and interpretation of physical and biological and biophysical phenomena related mainly to acoustic physics.
- Acquisition of statistical knowledge for the understanding of physical and biological phenomena.
Expected learning outcomes
Acquisition of basic knowledge of Physics, indispensable for understanding concepts that will be deepen in more specific courses, of Medical Statistics, to develop useful skills both for research, management and data processing and for the critical evaluation of scientific literature for a correct and more rigorous exercise of the profession and of Electrical and electronic measurements, to understand acoustic phenomena
Course syllabus and organization

Single session

More specific information on the delivery modes of training activities for academic year 2021/22 will be provided over the coming months, based on the evolution of the public health situation.
Prerequisites for admission
No specific preliminary knowledge is required beyond what is already foreseen in relation to the admission to the Degree Course which includes: General culture, Biology, Chemistry, Physics and Mathematics
Assessment methods and Criteria
The evaluation criteria are based on a written test, which can be followed by an optional oral test. The evaluation is expressed in thirtieths. During the written test, where relevant, the use of a calculator is allowed.

The test includes multiple choice questions which also include exercises. Furthermore, when considered of interest, open questions on specific topics covered in the course and with particular attention to those concerning the applications of interest for the degree course can also be included. The oral test consists of the discussion of the written test on subjects of the discipline and generally it is two questions.
Applied physics

Teaching methods
Lectures and exercises for an adequate use of the units of measurement and consolidation of the physical contents learned, including physical laws. Students will have all the PowerPoint files of the lessons available.

Medical statistics
Course syllabus
1. The statistical language
- what the medical statistician does
- data collection
- the measurement scales of the information collected
- how to summarize and describe the data
- critical interpretation of the data
- images and numbers as a description tool
- one thing at a time or several things together: describe individual aspects or describe relationships.
2. Uncertainty
- how to deal with uncertainty
- how to make it an instrument of knowledge
- know the probabilities and quantify the risks
- measurement errors and their distribution.
- an example of certain uncertainties: population screening
3. How to build knowledge
- epidemiological studies and clinical studies: what they are, how they plan, which tools they use
- the uncertain causal relationship: measuring the risks and understanding their significance in the epidemiological field
4. Know through (and despite) the case
- know how to use the appropriate rules
- from population to sample, from sample to population
- put trust in what I see to know what I don't see (inference)
- the confidence interval or perhaps a very precise one
