Introduction to the statistical software SAS. During the class the main Data Steps and Proc Steps required to solve simple problems of statistical data analysis are introduced. Moreover, the course involves SAS consultants and external teachers who use SAS for their working activities.
Provide the basis for manipulating and rendering data with the SAS system.
At the end of the course students will be able to:
use SAS software in order to autonomously tackle and solve simple problems of statistical data analysis, mainly descriptive analysis.
use SAS software in order to build and present reports of the analysis
read, understand, and use the on-line SAS manual and related example.
Basis of univariate and multivariate descriptive statistics
Lessons are held in a computer lab. After a theoretical part concerning SAS language an exercise is carried out by the students and the related solution is discussed collectively.
The course includes seminars by SAS consultants and experts who use SAS for their working activities.

The class will start according to the academic calendar.
The exam consists in a written test and in the preparation and submission of a statistical analysis carried out through SAS. Two additional points to be added to the final mark of the written test can be obtained by completing the first online course SAS Programming Essential suggested by the SAS consultants. The on-line course is considered completed aftear obtaining the corresponding SAS digital badge.
The written test aims at evaluating students’ ability to code simple SAS programs. The preparation and presentation of an activity carried out through SAS software aims at assessing to work independently and in a team.
Students with DSA disability or other special educational needs are recommended to contact the teacher at the beginning of the course in order to organize teaching and assessment taking in account both the class aims and the student's needs and providing suitable compensatory instruments.
Upon request by the students the lectures and/or the exam can be held in English.
