### Learning Objectives

The course aims to give students a methodological training and basic statistics, not separated from the acquisition of an operational capability in the face of real problems

### Program

1. Outline of probability.

2. Population and sample.

3. Measuring scale variables.

4. Main indices of position (arithmetic mean, median and mode)

and dispersion (variation range, variance, standard deviation, coefficient of variation,

quartiles, interquartile range).

5. bivariate statistics: regression and correlation.

6. Main distributions: Binomial, Poisson, Gaussian.

7. The sampling distributions: distribution of the sample mean and t-distribution.

8. Test: the z test; the Student t test (for one and two samples).

9. Confidence intervals for the means and proportions.

10. Anova and nonparametric statistics

11. The scientific method and unscientific methods

12. The research protocol

13. The rationale

14. The literature search

15. Randomization

16. Blindness

17. Experimental design

18. Sample size

19. Assessment tools and their properties: reliability, validity, responsiveness, least significant difference, sensitivity and specificity

20. Deviations from the protocol and their treatment

21. Critical reading a scientific paper

None

Assessment

Written test (multiple chioce quizzes regarding the theoretical part; exercises); the oral exam is optional (after passing the written test with at least 18/30 score)

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.

### Additional Information for Non-Attending Students
