DATA ANALYSIS

This course belongs to the interdisciplinary educational activities of the Data Science curriculum of the Bachelor in Informatics. The course aims at providing students with the basic instruments of statistical inference and data analysis. The objective of the course is to develop skills to solve statistical questions arising in technology, science, medicine, economics and business. Special attention will be paid to the integration of methodology with computational tools through the R language. The achievement of the educational objectives of the course will provide the student with the tools to learn more advanced data science methods.

Regular and active participation in the teaching activities offered by the course and in independent research activities will enable students to:
1. (knowledge and understanding)
-- acquire knowledge and understanding regarding basic inferential and data analysis methods
2. (applying knowledge and understanding)
-- synthetize and model phenomena characterized by variability and uncertainty
-- identify and fit statistical models for prediction
-- use statistical software for manipulation, synthesis and analysis of data
3. (making judgements)
-- correctly evaluate the outcomes of statistical software analyses

Students are assumed to have reached the learning objectives of the course Probability e Statistics (www.unive.it/data/course/230177) although it is not formally required to have passed the examination. It is important that the students have a solid familiarity with the main properties and operations involving discrete and continuous random variables.

The course program includes presentation and discussion of the following subjects:

1. Descriptive statistics
2. Graphical data summary
3. Point estimation
4. Interval estimation
5. Hypothesis testing
6. The Bootstrap method
Methods will be illustrated with simulated and real data using the R language (www.r-project.org).

The achievement of the course objectives is assessed through a written exam via Moodle. The exam consists of eight questions designed to measure
1. the theoretical knowledge of the course topics,
2. the ability to apply knowledge for solving real data problems.
The maximal score for each question is 4 points. The final score is the sum of the scores of the four exercises. A total score exceeding 30 corresponds to 30 with honors. During the written test the use of books, notes, or electronic media is *not* allowed.

Conventional theoretical lectures complemented by exercise classes and discussion of case studies. Teaching material prepared by the lecturer will be distributed during the course through the Moodle platform. The statistical software used in the course is R (www.r-project.org).
