Learning Objectives - Last names A-K
This course offers an introduction to measurement in Psychology: the concept of variable and levels of measurement are explained, the different way to gather data are presented, and how to prepare a matrix of data is illustrated.
Moreover, this course is designed to give students theoretical and practical knowledge of the descriptive statistics which allow them to construct frequency distribution, to measure and interpreter the measures of central tendency and variability, to standardize data, and to construct and to read graphs.
It's a further aim of the course to introduce students to the fundamental principles of probability theory, to probability distribution and sampling distributions. Students will also learn the logic of hypothesis testing and the confidence intervals.
Finally, it's our aim to ensure that students acquire the competence to report the results of descriptive and inferential statistic analyses.

Moreover, the course is designed to give students theoretical and practical knowledge of the descriptive statistics which allow them to construct frequency distribution, to take measures of central tendency and variability, to standardize data, to construct and read graphs.
It's a further aim of the course to introduce students to the basic principles of probability theory, to the mainly employed probability and sampling distributions. Then, starting from these prerequisites, hypothesis testing and confidence intervals are taught.
Finally, the course aims to ensure that students acquire the competence to report the results of descriptive and inferential statistic analyses.

Teaching Methods - Last names A-K
Psychological literature offers the framework to introduce statistic theoretical issues, that is statistics topics are presented through examples taken from different research area in psychology. Moreover, paper and pencil exercises (framed with psychological contents) are presented for each theoretical issues.
