Learning outcomes of the course unit

Main objective of this introductory course to data analysis is to let the student becoming familiar with the discipline, its logic and its tools. In particular the student should develop the skill to select data that are most appropriate to solve a question and by which tools such data can be appropriately analyzed.

Prerequisites

Elementary mathematics: summation, product, matrices, determinants, limits, derivatives.

Course contents summary

Main contents of the course are probability theory and related distributions (normal, binomial);experimental data and their treatment (tables, chartsm, hystograms) and the most important elementary statistical tests (Z, T, ANOVA, Regression, Correlation).

Teaching methods

Concepts are explained in classroom-taught lessons and exercises are assigned to the students to make the concept they have learned theoretically operational.

Assessment methods and criteria

Written examination in which the student is asked to solve a problem by applying the statistical test chosen among those covered in the course and answer spome theoretical questions related to the topics cevered in the course. Depending on the restrictions imposed by the Covid the exampination will switch to an oral presentation by means of the Teams platoform. To this and depending on the number of candidates the frequency of the examination dates may be changes as needed.
