Learning outcomes

At the end of the course, the student acquires both a good knowledge of the technical mathematical tools and their use and of the main basic methods and tools of the quantitative study of collective phenomena. He is therefore able to set and solve problems and assimilate new concepts from previous experience and knowledge. Furthermore, he is able to independently produce and process statistical data, developing the ability to interpret and critically evaluate statistical information.

Teaching methods

Mathematics (Module 1)
The teaching is divided into lectures and exercises in the classroom. Also as a consequence of the intensive nature of the lessons and their sequential structure, attendance is strongly recommended. During the course, examples from the sectors of animal husbandry, agronomy and agricultural engineering are taken into consideration.
Statistics (Module 2)
The teaching is divided into lectures and exercises in the classroom or in the computer lab. Given the capacity of the computer lab, the exercises may require a rotation, the modalities of which will be communicated during the course.

Assessment methods

The learning assessment of the entire course will be done through a final exam that includes a written test containing exercises related to the Mathematics module (maximum score 75) and the Statistics module (maximum score 25).
The detailed procedure for the proposed exercises, both in Mathematics and Statistics, will be required, complete with reasons for each answer. The number of exercises and the relative score may change based on the difficulty.
The duration of the test will be two hours and forty-five minutes.
The grade will be expressed in thirtieths and the written test will be considered passed if this grade is at least 18 out of 30 corresponding to 60 points out of 100 in the test, with the constraint on the Statistics part: the score achieved must be 15 out of 25.
PRAISE will be awarded to those who, in addition to earning 30, will answer an additional question included in the text of the written assignment.
The number of appeals is equal to two for the winter session, two for the summer session and two in the months of August and September.
