Course detail
Biostatistics
FEKT-BPC-STAAcad. year: 2022/2023
The course is an introduction to applied data analysis for students of biological and possibly clinical disciplines. The substance is discussed from theoretical principles (principles for statistical estimates, the existence of stochastic distribution, basic statistical tests), simple applications (one-sample and two-sample tests, correlation analysis) to the basics of stochastic modeling and experimental design (design of experiments, regression analysis, analysis of variance). Theory is always discussed in direct connection with practical examples. This course enables students to acquire the basic principles of biostatistical data analysis and prepares candidates for its sole use in their scientific work. The course will also focus on pratical training with the use of all available software tools (Statistica for Windows, SPSS).

Course curriculum
2. Continuous, ordinal and nominal data in biology. Estimates of selection parameters. The percentages and indices as derived biological data.
3. The distribution of continuous variables - testing hypotheses, graphical methods. The distribution of binary variables - testing hypotheses, graphical methods.
4. One-sample tests. Testing hypotheses about population parameters selection: sample mean, median, standard deviation, variance. Sampling and experimental design to test the parameters of the selection populations.
5. Application of binomial and Poisson distribution in biology, modeling using the binomial distribution. One-sample tests of binomial parameter pa Poisson's constant.
6. Comparing the two selection parameters populations. Experimental plans - a completely randomized pair. Parametric and nonparametric methods. Formal presentation of the comparison of two sample populations in the literature. Graphical methods.
7. The analysis of binary and ordinal data. Goodness: genetics, molecular biology, ecology. Analysis of R x C contingency tables, discrimination of categorical data. Binomial test and a test of homogeneity of binomial frequency.
8. Correlation analysis. Parametric and serial correlation (covariance, correlation coefficients, coefficients of similarity). Correlation and covariance matrix. Partial correlations.
9. Analysis of variance (ANOVA) models a simple classification for experimental and ecological data. Non-parametric methods of analysis of variance.
10. Way classification ANOVA, testing the interaction of one or more experimental interventions, formal presentation of the results of analysis of variance.
11. Introduction to regression analysis. Regression analysis of the line. Analysis of variance in the regression analysis line. Linear regression. Residual analysis of regression models.
