Biostatistics, Principles and Applications


At the end of this course the students should: 

1. Explore the main sources of statistical information on health and recognize the most commonly used indicators in decision-making

2. To distinguish the various types of data, their scales of measurement and the most appropriate way to organize information in charts and graphs

3. Build and interpret frequency tables

4. Calculate and interpret descriptive statistics measurements (central tendency and dispersion)

5. Explore and synthesize data in healthcare, according to their different characteristics

6. Calculating odds for classical definition and using the axiomatic, including conditional probabilities

7. Describe dependence / independence factors, its impact and importance in the context of Health

8. Describe a random variable and understand the use of models to calculate odds

9. To characterize the probability distributions Binomial, Poisson and Normal and calculate probabilities from these models

Teaching method

The curricular unit is divided into 6 topics that include lectures and videos of oral exposition of the contents, along with the presentation of examples and complemented by solved proposed exercises. At the end of each topic a revising exercise is delivered. During the curricular unit the students will present one evaluation assignment, contributing for the final grading. A timetable for explaining doubts to students made is available.

Evaluation method

Evaluation: exam and assignment (each 50%)
