Scientific Production and Biostatistics

Descriptive statistics.

Classes consist of a theoretical exposition of the subject but always accompanied by practical examples so that thereis a better and easier understanding of it. The resolution of practical exercises is done using the SPSS computersupport, thus making it possible to apply the material taught to real cases.

It is intended that the student has a current and comprehensive view of the main methods and techniques to be taken into account in the development of research work in the field of health sciences. The student must also acquire skills to understand the conditions underlying the applicability of the theoretical models used for statistical analysis, as well as analyze and interpret the results obtained. Students should also be able to use the SPSS (Statistical Package for Social Sciences) computer application to solve problems involving the concepts developed in the course unit.

Introduction to scientific research:
Common Sense vs Scientific knowledge;
Problem, Research question;
Research hypotheses.
Stages of an investigation.
Variables and Types of scientific research.
Psychometric Characteristics: Fidelity and validity.
Sampling methods and determination of Sample size.
Statistical strategy.

Hypothesis Testing: type I and type II error, significance levels, power and p-value in statistical tests.
Statistical inference on the parameters of normal and non-normal populations (larger population).
Nonparametric Statistics: study of a population and compare two or more populations.
Tests for independence and homogeneity: contingency tables.
