Course objectives
The aim of the practical exercises is to learn how to effectively use the R software to calculate statistical tests and models appropriate to a given experimental design, and to interpret the output of the models correctly.
Learning outcomes
Passing through this practical training, students should be able to: - devise the adequate design of experiment; - select appropriate statistical method for given biological experimental data and design; - analyze these data using R software; - present obtained result using reports, graphs and tables.
Syllabus
  • - Data collecting. Organization of data for statistical analysis in R.
  • - Data import from spreadsheets. Variable types, statistical distributions, quantiles, hypotheses testing, null and alteantive hypothesis, I. and II. error type.
  • - Experimental design, selecting of appropriate statistical method.
  • - X2 test. F-test, t-test. One-way analysis of variance, homogeneity of variances, independence of residuals, data transformations, contrasts, a priori and post-hoc tests.
  • - Multiple analysis of variance: factorial, nested, and block designs, repeated measures ANOVA; interaction, fixed effects and random effects models, mixed model.
  • - Covariance analysis. Correlation analysis, Pearson, Spearman and partial correlation coefficient.
  • - Regression analysis, linear and non-linear regression, multiple regression.

Teaching methods
Practical lectures focused on theoretical aspects as well as practical applications. Practices in a computer room focused on training of regression modelling in R software.
Assessment methods
Knowledge will be evaluated using model examples calculated by students during the whole semester.
