Qualifications

• Know about the roles of quantiles, variances, standard deviations and correlations to measure risks.
• Know the axioms of a discrete probability space.
• Know the most important distributions and their properties.
• Know the importance of the central limit theorem.
• Can describe univariate and bivariate data according to the level of scale using numerical measures and graphical representations.
• Can explain the content of the axioms of a discrete probability space while modelling a random experiment.
• Use the law of large numbers to interpret a probability as a relative frequency in the long run.
• Can explain why and when a certain distribution is used to model economic situations.
• Can name the basic idea of testing hypotheses referring to the possible types of errors.
• Name the basic ideas of standard testing procedures.
• Calculate the critical values in the decision rules of binomial tests.
• Can explain the meaning of confidence intervals and indicate the duality between confidence intervals and testing hypotheses.
• Use the principle of ordinary least squares to estimate the parameters of a regression model.
• Run simple linear regressions, set up the ANOVA-table and judge the residual plot.
• Calculate probabilities using addition rules, decision trees and combinatorics.
• Can explain the results of Bayes' theorem.
• Use limits theorems to approximate distributions and probabilities.
• Use calculations rules for expectations and variances correctly and can explain their meanings in the context of risk measuring.
• Calculate the critical values of binomial tests and the resulting probability of a type 2 error.
• Evaluate the test statistics of standard procedures, read the corresponding critical values from statistical tables and formulate the conclusion of the testing procedure correctly in the given context.
• Calculate confidence intervals and interpret them correctly in a given context.
• Interpret measures as quantiles, variances, standard deviations, correlations, skewness, curtosis correctly.
• Use the vocabulary introduced to them to describe graphical representations correctly and include the advantages and disadvantages of such representations while interpreting them.
• Judge the certainty or uncertainty of statistical conclusions and formulate their interpretations accordingly.
• Judge the practical relevance of a linear regression in the given context.
• Judge the uncertainty in the conclusions from statistical testing procedures correctly
• Know the central statistical techniques that are often used in business applications.
• Understand the meaning of statistical notions.
• Use the concepts introduced in a purposeful way, interpret the results in the context and formulate their conclusions correctly.
• Use basic commands of the software package R to analyze data graphically and numerically.
• Apply standard learning techniques in abstract contexts so that they get used to working with scientific publications on their own.
• Analyze data to justify decisions in business applications.
• Analyze business cases using methods of probability theory.
