CODE 118394 ACADEMIC YEAR 2025/2026 CREDITS 3 cfu anno 1 SCIENZE E CULTURE AGROALIMENTARI DEL MEDITERRANEO 11758 (L/GASTR R) - IMPERIA SCIENTIFIC DISCIPLINARY SECTOR SECS-S/02 LANGUAGE Italian TEACHING LOCATION IMPERIA SEMESTER 1° Semester MODULES Questo insegnamento è un modulo di: STATISTICAL, OPERATIONAL AND CHEMICAL RESEARCH OF TECHNOLOGIES AIMS AND CONTENT LEARNING OUTCOMES The main objective of the module is to provide students with the key inferential tools used in experimental contexts. By the end of the course, students will be able to: Understand the basic principles of sampling and experimental error. Apply basic statistical tests (e.g., t-test, chi-square) to compare groups and test hypotheses. Evaluate statistical results in relation to the experimental context, with a critical and informed approach. AIMS AND LEARNING OUTCOMES The learning objectives that will be evaluated for the purpose of passing are summarized in the following scheme: Knowledge and understanding: Knowledge of probabilistic techniques for the analysis of simple random phenomena; acquisition of basic statistical inference tools for estimation and hypothesis testing. Ability to apply knowledge and understanding: Ability to carry out simple computations in situations of uncertainty; know how to apply the main statistical inference techniques; know how to read statistical analyses carried out with the methodologies presented in the course. Making judgements: Be able to understand and comment on the results obtained from statistical analyses in practical examples based on the context of the application, thus being able to use the results in decision-making processes. Communication skills: Acquire the basics of technical statistical language to communicate clearly and without ambiguity with both statisticians and non-statisticians. Learning skills: Be able to correctly read the results of statistical analyses, also in contexts of greater complexity than those presented in the course. PREREQUISITES None. TEACHING METHODS Blended teaching, with on-site and online classes. SYLLABUS/CONTENT Part I: Probability Random experiments, outcomes, events. The probability function and its axioms.

TEACHERS AND EXAM BOARD CORRADO LAGAZIO Ricevimento: Tuesday 16.30-18.00 Teacher's office For Imperia: I am available after lessons during the first semester, and throughout the year on Teams by appointment via email LESSONS LESSONS START https://corsi.unige.it/en/corsi/11758/studenti-orario Class schedule The timetable for this course is available here: Portale EasyAcademy EXAMS EXAM DESCRIPTION The partial exam for the open badge consists of a written/practical test with multiple-choice questions and some exercises to be solved using Excel. ASSESSMENT METHODS The multiple-choice questions are designed to assess the knowledge and understanding of the topics covered in class, while the exercises are intended to evaluate the student's ability to apply the methods learned. FURTHER INFORMATION Working students and students with DSA certification, disability or other special educational needs are advised to contact the teacher at the beginning of the course to agree on teaching and exam methods that, in compliance with the teaching objectives, take into account individual learning methods.
