Language
ITALIAN. Topics below divided in 4 parts: 1) GENERAL INFORMATICS 2) APPLIED PHYSICS 3) BIOMETRICS AND MEDICAL STATISTICS 4) STATISTICS FOR THE EXPERIMENTAL AND TECHNOLOGICAL RESEARCH
Prerequisites

1) =
2) Topics already learned at the high school such as: the concept of equation and the basic rules for its solution, the representation of digits in the scientific notation as power of ten with positive and negative exponent; logarithms and their properties; the definition of function; the cartesian representation of a graph of a straight line, a parabola, a hyperbola and an exponential function; the trigonometric functions; the measure of the angle in radiants; the surface areas and volumes of some geometrical figures (triangle, rectangle, circle, cube, sphere)
3) The course is part of the students' basic training together with Physics, preparatory to the lessons and activities in the haelthcare field. To better follow the course, the student must have basic knowledge of mathematics of scientific high schools’ program.
It is mandatory for Statistics for research and technology course.
4) The course is part of the basic training of students: together with Physics, Medical Statistics and Computer Science, it is a prerequisite for lessons and activities in the healthcare field. To better follow the course, the student must have attended and acquired basic skills in Medical Statistics and Biometrics.
Learning outcomes

1) The course is aimed at realization of the main methods of statistical
analysis using a common program such as Microsoft Excel (2010 version).
At the end of the course the student will have learned the elements for:
Learn how to build a data matrix; Build graphical representations;
Analyze the data both from descriptive point of view that analytical; The
interpretation of the results.
2) The aims of the course are:
a) to instill in the student the fundamental topics of Physics for the comprehension of biological and biomedical phenomena
b) to impart the meaning of scientific method
c) to teach the student how to apply the principles and law of Physics to specific problems, in particular the biological and biomedical ones
At the end of the course the students must be able to:
a) find the fundamental physical quantities which are involved in the description of a physical phenomenon
b) schematize the physical phenomenon with a model which could represent the fundamental characteristics of the system under study
c) formulate physical laws of the system under study, if they derive from general principles or they are of empirical origins, and represent them in an analytical or graphical form
d) analyze from a quantitative point of view the inter-dependence among two or more physical quantities
e) integrate all the knowledge acquired for the resolution of a specific problem
3) The course of Medical statistics and Biometry aims to provide the methodological principles for a scientific approach to the study in healthcare field. It is the first step in the knowledge that an operator in the healthcare field must have in order that the scientific research carried out is correctly set and evaluated.
In detail, the course aims to develop the theoretical and practical knowledge of the most frequent descriptive statistical methodologies (knowledge and comprehension), as well as the ability to correctly apply this knowledge both to new experimental situations and to published research studies (ability to apply knowledge and comprehension).
At the end of the course the student will be able to independently perform basic statistical analyses and communicate in an appropriate way the findings, as well as to understand and critically evaluate the published evidences in relation to their work context.
4) The course gives tools for bivariate analysis and interpretation of data in healthcare area.
In detail, the course aims to develop the theoretical and practical knowledge of the most frequent inferential statistical methodologies (knowledge and comprehension), as well as the ability to correctly apply this knowledge both to new experimental situations and to published research studies (ability to apply knowledge and comprehension).
At the end of the course the student will be able to independently perform basic statistical analyses and communicate in an appropriate way the findings, as well as to understand and critically evaluate the published evidences in relation to their work context.

Teaching methods

1) The course is based on taught lessons and practical applications through pc with resolution of statistical problem using excel
In particular students will have to attend taught lessons at one of the computerized classroom of the University.
2) Front side lectures
3) The course is organised in lectures and practical exercises. With the problem solving approach, the fundamental elements of Medical Statistics will be addressed.
Practical exercises aim to the interpretation and comprehension of evidences deriving from the right application of methods medical statistics.
4) The plan of the course is based on academic lectures and practical section (problem solving approach).
The course is organized in lectures and practical exercises. With the problem solving approach, learners will be introduced to the correct application of inferential analysis procedures and interpretation of results.
Practical exercises are not aimed at the application of theoretical concepts on experimental data sets, but at the interpretation / comprehension of scientific evidence deriving from the correct application of inferential statistics techniques.
