Course objectives

Aim of the course is to introduce methods, techniques and related computer science instruments for the analysis of experimental data.

It  provides the basic knowledge to use   programming languages  for statistical computing and graphics (e.g. R programming language)

Results of learning outcomes

KNOWLEDGE AND UNDERSTANDING – Completing the course students will be able to:

1) use suitable descriptive and inferential statistics techniques to describe and understand the phenomena being studied;

2) manage suitable computer science instruments such as worksheet or dedicated software programs for statistical data analysis.

APPLYING KNOWLEDGE AND UNDERSTANDING – Students will perform the statistical analyses required by the problem under study by selecting the most computationally and graphically suitable computer science support.

MAKING JUDGEMENTS – Students will decide which statistical techniques to use according to the available data sets to describe and understand the phenomena under consideration.

COMMUNICATION – The student will be able to justify the choices for the analysis to be performed and to give a synthetic description of the techniques employed and of the results obtained.

Program

• Introduction to Data science;

• Visualization using ggplot2;

• Basic R functionalities:

  • Data structures: vector, matrix, list and data frame, tibble;

  • Apply operators;

  • Input/output operator;

  • Package and library.

• Tidy data in R

• Data Transformation;

• Programming with R:

  • Function;

  • Flow control: if,for, while, break ... statements;

  • Debugging in R.

Course delivery

The course consists of  10 hours of lectures and 14 hours of laboratories. Laboratories include exclusively practical activities.

The lectures will be in presence with exceptions in accordance with university regulations.

The slides presented during lectures are available to students as online materials.

Attendance of lessons is not mandatory, but highly recommended due to the necessity of learning and employing specific computer science instruments.

Learning assessment methods

The exam consists of an oral test  and requires a practice exercise on R  programming languages
