Course objectives
The course is based on principles of basic methods of medical data analysis with respect to particularities of data files in the neuroscience research. The main emphasis will be laid on correct application of the methods and interpretation of results. Theory will be followed by practical demonstrations in software SPSS or another software which is freely available at Masaryk University.
  • 1. How to describe and visualize medical data correctly: Types of medical data and their visualization. Data preprocessing. Descriptive statistics – mean, median, quantiles, variance, standard deviation.
  • 2. How to test medical data correctly: The most important model distributions - normal distribution, Student’s t-distribution, chi-square distribution, etc. Data transformation – normalisation, standardization, categorization. Confidence intervals. Formulation of hypotheses in medical research – the null and alternative hypotheses. The significance level and power analysis. p-value.
  • 3. How to use parametric and non-parametric tests I: Proper choice of the type of the test in various situations. One-sample tests – z-test, one-sample t-test, paired t-test. Two-sample t-test. Non-parametric tests – Wilcoxon test, Mann-Whitney test etc. F-test.
  • 4. How to use parametric and non-parametric tests II: Analysis of variance (ANOVA) and its assumptions. Multiple testing problems and correction procedures – Bonferroni correction, FDR. Correct application of these corrections. Kruskal-Wallis test.
  • 5. How to analyse categorical and binary data I: Analysis of contingency tables – Pearson’s chi-square test, Fisher’s exact test, McNemar’s test. Relative risk and odds ratio. Binomial and Poisson distribution.
  • 6. How to analyse categorical and binary data II: Analysis of diagnostics tests – sensitivity, specificity, positive and negative predictive values, likelihood ratio. Examples of correct and incorrect analyses of power of diagnostic tests. Detection of diagnostic cut-off points using ROC curves.
  • 7. How to analyse associations between continuous variables and how to use basic regression models: Basics of correlation analysis – Pearson’s and Spearman’s correlation coefficients. Basics of regression analysis – linear regression, regressing out covariates.
  • 8. How to analyse survival of patients: Survival analysis. Cox regression.

Teaching methods
Teaching is interactive and based on solving real problems and examples. The examples and study materials will be available beforehand. During the first lecture, students will be told to prepare examples of problems in their analyses (PhD theses, research activities etc.). These problems will be discussed and solved in following lectures.
Assessment methods
Course is finished by colloquium, consisting of analyses of sample data files using computer.
Language of instruction
Further comments (probably available only in Czech)
The course is taught annually.
The course is taught: in blocks.
Note related to how often the course is taught: 8 dnů po 3 hod.
