Course objectives
Students will get acquainted with basic statistical methods for evaluation of experimental data in human biology and will learn to use them on real data.
Learning outcomes
Student will be able to:
- to choose appropriate statistical methods for evaluating specific experimental data in human biology;
- interpret the results of statistical evaluation of the data
  • 1) basic terms: types of data (nominal scale, ordinal scale, interval scale, and ratio scale), descriptive statistics, definition of probability, principle of statistical hypothesis testing, statistical software
  • 2) probability distribution: discrete and continuous distribution, qualitative and quantitative data, examples of discrete distributions, examples of continuous distributions, basic characteristics of data
  • 3) data visualization: scatter plot, histogram, box plot, outliers
  • 4) statistical evaluation of qualitative data: contingency table, Chi-squared test, Fisher's exact test, Odds Ratio (OR), Risk Ratio (RR)
  • 5) statistical evaluation of association study: types of association studies, selection of date for association study, statistical evaluation of genome-wide association studies (GWAS), problem of multiple comparisons: Bonferroni correction
  • 6) determination of measurement error in qualitative data: inter-observer error, intra-observer error, kappa coefficient
  • 7) parametric tests for statistical evaluation of quantitative data: normality tests, unpaired t-test, paired t-test, F-test of equality variances, ANOVA, post-hoc tests
  • 8) nonparametric tests for statistical evaluation of quantitative data: Sign test, Wilcoxon test, Mann-Whitney test, ANOVA, Kruskal-Wallis test
  • 9) relative gene expression analysis: calculation of relative gene expression, selection of a suitable test
  • 10) correlation analysis: Pearson' correlation coefficient, Spearman's rank correlation coefficient, basics of linear regression, linkage disequilibrium
  • 11) determination of measurement error in quantitative data: TEM, reliability coefficient
  • 12) estimation of relatedness: Bayes' theorem, conditional probability, principle of paternity testing based on DNA
