Course objective
C1. The main aim of the course is to teach the students about the methods and the procedures of descriptive statistics and mathematical statistics.
C2. The students learn about the basic methods and the goals of descriptive statistics like using statistical measures, graphs, and about the methods of statistical inference, like estimation and principles of statistical tests.
Prerequisites
W1. Introduction to differential and integral calculus
W2. Foundations of probabilistic methods

SOCIAL COMPETENCE
K1. Students are able to enter into discussion about the statistical inference and the methods of statistics (K_K07).
Teaching method
Lecture (with elements of discussion), individual work, exercises, using software applications devoted to statistical inference.
Course content description
1. The main aims and drawbacks of statistics – examples of statistical problems, basic definitions (population, sample, random variable), measurements scales.
2. Basic statistical concepts – empirical distribution, data series, time series, types of data, quantity, cumulated quantity.
3. Measures of descriptive statistics – average, median, quartiles, quantiles, mode, standard deviation, variance, range. Other measures of descriptive statistics.
4. Statistical graphs – histogram, box-and-whisker plot, pie plot, line plot, other plots.
5. Review of some random variable distributions – discrete distributions and continuous distribution (binomial distribution, Poisson distribution, normal distribution, exponential distribution, t-Student distribution).
6. Estimation – point estimation, estimator features, method of moments, maximum likelihood estimation, methods and examples of the interval estimation.
7. Statistical tests – the concept of null hypothesis, alternative hypothesis, significance level, types of errors, critical value. Example of the tonstruction of the statistical test.
8. Selected examples of statistical tests (chi-square tests, tests of means, Kolmogorow-Smirnov test etc.).
9. Introduction to multivariate analysis, concept of the dependence of variables (covariance and correlation factor). Foundations of regression analysis (linear and nonlinear).
10. Time series – time series smoothing, indices of dynamics. Discussion about basis of the time series forecasting.
11. Introduction to simulation methods – the Monte Carlo method and its applications.
