Acquisition of the theoretical knowledge and of the practical skills at the basis of the main data analysis techniques . At the end of the course , the student will be able to recognize which statistical approach has to be adopted in specific contexts and to comment on the results of these analyses .

The program is divided into 13 topics :

1 . introduction and key concepts (week 1)

2 . Simple regression (week 2)

3 . multiple regression (week 3)

4. Comparing Means: t - test (week 4)

5. Comparing Means : one-way ANOVA (week 4)

6. General linear model: factorial ANOVA between- subjects (week 5)

7 . Post- Hoc Comparisons: the problem of multiple comparisons and of statistical power  (week 5)

8. General Linear Model: Model Assumptions (week 6)

9. Nonparametric tests (week 6)

10 . Subject assessment: assessment tools , reliability and validity (week 7)

11. Statistics applied to neuropsychology and psicodiagnosis (week 7)

12 . Methods for the study of individual patients. (week 8)

13 Factor analysis (week 9)

+ 3 practical lectures + 1 practical meeting

Metodologia della ricerca con elementi di statistica

The student must show that he has

- Knowledge and understanding of the fundamental concepts of hypothesis verification and statistical tests in the theoretical framework of the general linear model. Moreover, he/she must understand the methods underlying validation and standardization of the psychological measures

- Applied knowledge and understanding: acquired the ability to recognize which statistical approach to use in different practical contexts

- Making judgements: Acquired the ability to use knowledge and concepts for describing the results of the main statistics used in the psychological field

- Communication skills: acquired specific lexicon for the description of psychometric results

- Learning Skills: At the completion of the course students will have gained a good degree of autonomy in reading the materials related to the validation of psychometric tests and in the critical understanding of the adequacy of the statistical analyzes reported in the psychological research.

The teaching material prepared by the lecturer in addition to recommended textbooks (such as for instance slides, lecture notes, exercises, bibliography) and communications from the lecturer specific to the course can be found inside the Moodle platform › blended.uniurb.it

There are 4 practical lessons (using the PC) to illustrate

1) How to build a database for psychological research?

2) How to perform the statistical analyses described in the front lessons

3) How the results of these analyses should be read and reported

Practical lessons are essential for passing exams

In addition, a seminar is planned for the practical demonstration of the psychophysiological testing and correction of psychological instruments

Teaching

Theorethical and practical lectures

Innovative teaching methods

Attendance

Not mandatory

Course books

1) Gallucci, Leone e Berlingeri “Modelli statistici per le scienze sociali” (II edizione)

2) Chiorri "TEORIA E TECNICA PSICOMETRICA" 2/ED - (Capitolo 1, 2, 5, 7)

Assessment

The exam consists of two tests,

1) Written multiple structured answer test to assess the knowledge and arguments that will be dealt with in the different parts of the course. The test consists of 30 questions, each question includes 4 alternatives. Each question has a value of 1 point. There is no penalty in case of an incorrect response.

2) Written commentary of a series of statistical analyses. In this case the student is provided with the results of a series of statistical analyses carried out for psychological research. It requires the student to produce, for each reported result, a written comment using a specific language.

In order to pass the examination it is necessary to take at least 18 in both tests, the final vote will be given by the average of the marks obtained in the two trials.

Competence level will be scaled as follows:

· less than 18: insufficient

·  18-20: sufficient

·  21-23: completely sufficient

· 24-26: good level

·  27-30: optimal level

· 30 e lode: excellent level

Disability and Specific Learning Disorders (SLD)

Students who have registered their disability certification or SLD certification with the Inclusion and Right to Study Office can request to use conceptual maps (for keywords) during exams.

To this end, it is necessary to send the maps, two weeks before the exam date, to the course instructor, who will verify their compliance with the university guidelines and may request modifications.

Teaching

Theoretical and practical lectures

To allow students and non-attending students to compensate for what is done during the lessons with independent study, we recommend using all the materials included in the Blended Learning platform (videos, exercises, supplementary material, examples of questions exam) particularly useful for fully understanding the contents of the program.
