HEALTH ASSISTANCE

Objectives

GENERAL TARGET

At the end of the course students should be able:
To use epidemiological and bio-statistical tools for a better understanding of biomedical information and for improving medical decision making.

INTERMEDIATE TARGETS
At the end of the course students should be able to:

Organize collected data;
• Construct and interpret graphs;
• Describe the differences between the different measuring scales;
• To calculate the most common indices of central trend and variability of the data;
• Analyze frequency distribution curves;
• Use some inferential statistical techniques.

Autonomy of Judgement: At the end of the course students should be able to reading articles related to topics related to the CdS with significant content of biostatistics.

Communication skills: At the end of the course students should be able to use the technical language of medical statistics

Contents

The course aims to provide the basic knowledge of medical statistics for the analysis of biomedical data and the interpretation of the phenomena analysed.

Extended Syllabus

• Purposes and methods of statistical analysis; Statistical characters and classification.
• Data synthesis Tools: absolute, relative, cumulated frequencies; Arrangement and organization of data in tables; Frequency distributions.
• Main graphical representations: orthograms, circular field diagrams, histograms, frequency polygons, scatter diagrams.
• Central trend indices: Arithmetic mean and its properties, mode and median, Terzili, quartiles and percentiles.
• Variability indices: range, deviance, variance, standard deviation and coefficient of variation. Box-Plot.
• Frequency distribution curves. Symmetry indices.
• Normal distribution, standardized normal distribution.
• Confidence interval for an arithmetic mean and for a proportion.
• Concept of statistical hypothesis testing.
• Relationship between two qualitative characters: the Chi-squared test as a measure of association between two qualitative variables, the chi-squared with the correction of Yates for the continuity, the exact Fisher test.
• Student T-test for independent samples and student T-test for paired samples.
• Relationship between two quantitative characters: regression analysis and correlation analysis
• Critical reading of articles related to topics related to the CdS with significant content of biostatistics.

Teaching Methods

The teaching is structured in 20 hours of frontal didactics, each lesson will be divided into two parts. A first part in which will be presented the topic of the lesson and in a second part in which will be proposed by the teacher of the exercises that allow to verify the practical application of the topics treated in a theoretical way.

Evaluation methods

Verification of learning:

The verification of the preparation of the students will be done by written examination composed of multiple answer questions and/or exercises that allow to verify the practical application of the subjects covered. The total points (30) will be divided on the basis of the questions present on the task and reported on the text in relation to each individual test question. There is no oral test.
The duration of the test is 30 minutes.
The teaching methodology and the methods of verification will be presented by the teacher at the beginning of the course.
