Learning objectives
Initially the course aims to illustrate the use of the Microsoft Excel © computer tool, through the practical use of this software the students will learn how to organize and analyze a real set of data and present the main concepts of statistical reasoning first in the context of descriptive and then inductive logic through practical examples. Finally, with the introduction of statistical inference, elements of probability calculation and theory of random variables will be shown for the purpose of validating them.
Prerequisites
The only useful prerequisite, not mandatory, is related to the knowledge of the use of the PC, mainly as regards the file's creation of file's management regards that will be produced in the classroom.
Course unit content
With the course "LABORATORIO DI INFORMATICA APPLICATO ALLA RICERCA INFERMIERISTICA E OSTETRICA", students have the opportunity to concretize and deepen those statistical knowledge which, in the professional scenario, will allow to face and solve simple and complex problems. These concepts will be familiarized through learning and deepening of the Microsoft Excel © computer tool.

Teaching methods
The teaching will take place using mainly practical teaching methods (essential for a good applied computer science laboratory). There will be interactivity and the involvement of students, who are asked to actively participate in order to improve the concrete approach of the course.
we will start from the main concepts of the Spreadsheet and then deepen all the functions and features.
Therefore, through a parallel theory / exercises approach, we will move from the formal aspect of the formula or the statistical model to its algorithmic conversion to end with the use of the most appropriate algorithm based on the context of the available data.
Particular attention will also be made to the presentation and description of the processed data, relevant aspect for the production of an effective analysis report (presentation or article).
Assessment methods and criteria
Learning and the degree of preparation achieved is verified through a practical test using the PC and Microsoft Excel® software. All topics covered during the cycle of lessons are the subject of the test.
During the cycle of lessons, practical exercises will be performed in order to bring out any need for further study (it is strongly recommended that additional exercises carried out individually to increase awareness and learning of the topics).
