Learning objectives
The study of the environment and impacts on health is a complex and challenging job requiring solid scientific and technical competences.
The aim of this course is to give students the basic mathematical and statistical knowledge that are necessary to cope with quantitative activities related to science of life. To reach this aim, it is important that students understand which are the internal structures and the essential procedures of Mathematics and Statistics in order to be able to apply them in their future technical and professional activities.
Expected learning outcomes
At the end of the course students are expected to be able to:
Develop a logical and mathematical reasoning
Solve problems with differential and integration calculus
Develop basic mathematical models
Select the most appropriate statistical procedures for scientific and laboratory applications

Students will achieve knowledge of:

Fundamental aspects of differential and integral calculus as a base for further courses in their degree program
Fundamental statistical and probabilistic methods as a base for software instruments used in biological and pharmacological laboratories.
Course syllabus and organization

Single session

Responsible
Lesson period
First semester
Whenever possible, some lectures will be held in presence while the remaining lectures will be held remotely, during the class timetable, via Microsoft Teams. The lectures will be recorded.
Details about the class timetable will be available in Ariel platform.
In case of emergency, lectures will only be held remotely via Microsoft Teams and will be recorded.
Exams
In case of emergency the first partial, currently planned in precence, will be taken remotely via Microsoft Teams according to the University guidelines. The second partial will only be taken remotely.
Moreover, in case of necessity, the general exam will be taken remotely as well and the duration will be one and half hours instead of two hours.
Operative details will be available in the Ariel platform.

Assessment methods and Criteria
Written modality, score out of 30, either with two partials or general exam.

Modality with two partials: the first test on mathematics , the second one on statistics. The two partials will be taken during the course.
Each test lasts 1 hour. The first test weights 60% of the final score, the second one weights 40% of the final score.

The general exam lasts 2 hours and consists in 3 open answer math questions and two open answer questions on statistics plus a question on theory (either on mathematics or on statistics).
