Learning objectives

The course aims to enable the student to know and to understand the essential elements of the epidemiology and of statistics useful for nursing research, also in order to achieve the ability to use the knowledge and understanding gained in planning a search for the preparation of the thesis and thereafter conducting a professional activity based on "Evidence-based nursing".
Learning Outcomes
The student at the end of the course, will have to demonstrate knowledge and understanding about:
- basic concepts of epidemiology
- basic principles of medical statistics
The student also, applying the knowledge and understanding acquired, must be capable of set up the necessary steps of preparation of his/her thesis.

Course unit content

The lessons deal with elements of epidemiology and statistics useful for the planning of scientific research. The degree thesis is also used as a model for planning a research.

Teaching methods

Lectures will be held on-site in compliance with safety standards, provided that further instructions on the ongoing health emergency are not implemented. Supporting material will be available on the specific, student-reserved platform (Elly) and will include slide presentations, audio-video aids or video-recording of the lectures.

Assessment methods and criteria

The assessment of the achievement of the objectives foreseen by the course includes a written test with multiple choice questions.

In case of the persistence of the health emergency, the exams will be conducted remotely, as follows:
structured written test conducted remotely (by Teams and Elly). The candidate will remain connected with microphone and video camera turned on and will carry out the test under the control of the commission.
The test consists of multiple choice questions on the course contents (reference texts + documents uploaded to Elly during the course). There is no penalty for incorrect answers. Consultation of the didactic material will be allowed.
The final mark, reported directly on Esse3, will correspond to the arithmetic average of the assessments obtained in the written test.
