Course description for academic year 2017/2018

Descriptive statistics: populations and samples, measures of central tendency, measure of dispersion as well as measure of covariance.
Probability calculations and combinatorics: Conditional and unconditional probabilities, tree diagrams, dependence and independence.
Stochastic variables, expected values and variance. Simultaneous probability distributions.
Confidence Intervals and different types of hypothesis testing; t-test, chi-square test etc.
