Not applicable

History and development of Statistics Descriptive statistics.

Timely and/or interval estimation (confidence intervals) Choice of statistical test. Parametric hypotheses testing Student's t test Analysis of Variance: one factor and two factors Adjustment quality tests: Chi-square and Kolmogorov-Smirnov. Nonparametric hypotheses testing Reference to the Mann-Whitney test, Kruskal-Wallis and Wilcoxon test for ordinal variables, and McNemar's test for nominal variables Contingency tables Analysis of contingency tables Tests of independence Covariance. Correlation. Linear regression. Pearson's correlation coefficient. Dispersion diagram. Method of least squares

The teaching-learning methodologies include various instruments, based on masterly/tutorial teaching and theoretical-practical, face-to-face teaching. Other non-face-to-face instruments (e.g. moodle) complete and diversify the options available. The theoretical-practical classes aim to deepen and practice the topics taught in the theoretical classes, thus providing more direct contact with these topics. The assessment system is preferably continuous and consists of 2 written tests (40% each) and a practical group assignment (15%). Attendance at theoretical-practical classes and participation in solving the proposed exercises count towards the final grade, contributing 5%.   The final exam regime applies to students who opt for it, students who fail the continuous assessment, and those who request a grade improvement, covering the entire syllabus.
