Prerequisites:

The mathematical knowledge necessary for the admission to the undergraduate course in Psychological Science is assumed. 
Target skills and knowledge:

The probability that a woman of age 40 has breast cancer is about 1 per cent. If she has breast cancer, the probability that she tests positive on a screening mammogram is 90 percent. If she does not have breast cancer, the probability that she nevertheless tests positive is 9 percent. What are the chances that a woman who tests positive actually has breast cancer? This class presents some basic techniques for the analysis of the uncertainty inherent in statistical information, with the goal of providing a correct evaluation and communication of risk. Basic notions of elementary probability theory and of Bayesian probability are introduced and discussed, and their application is illustrated in problems connected with the medical and psychological practice. 
Examination methods:

Written final exam with open questions or quizzes (46 exercises; duration: 7090 minutes). The written exam verifies that the expected learning outcomes are actually acquired by the students through applicative questions, possibly including brief theoretical questions regarding the material presented in class.
The students will also make an oral presentation of a selected topic during class (topics chosen and researched by the students, under guidance of the instructor, working in groups of 34 people). Attendance to other students' presentations is considered part of the required coursework. 
Assessment criteria:

Grading is based on the results of the final written test, and on the performance in the oral presentation (the presentation contributes about 20% to the final course grade). 
Course unit contents:

Uncertainty in statistical information. Problems related to the evaluation of risk and communication of risk. Realworld examples. Bayesian inferences through the use of probabilities and by means of natural frequencies. Suitability of the latter for a more intuitive and direct insight in both risk estimation and in a transparent representation of risk. Examples focussing on the correct judgement of the probabilistic predictive value of medical diagnostic tests, and aiming at avoiding misleading risk information. Evaluation of the effect of interventions: Relative risk and Absolute Risk, and Relative and Absolute Risk Reduction (or Increase); Number Needed to Treat or to Harm [ARR, RR, RRR, NNT, NNH]. 
Planned learning activities and teaching methods:

Class lectures, with presentation of the main points mentioned above. Some theory and many examples. Recitations and exercises to complement the theoretical parts, also directly involving students in both individual and group work. The main focus is on realworld applications of the topics treated during the coursework. 
Additional notes about suggested reading:

The textbook is required reading, and further material is made available through moodle during class. See also the extra reading material indicated in the references below.
