Statistics and Probability

The course deals with the role of statistics and probability calculations in mathematics, as well as how statistical surveys can be designed, carried out and based on the school‘s values ??and assignments. The course deals with descriptive statistics with graphs, statistical measures and relationships such as regression and correlation, probability theory with studies of independent events and conditional probabilities, random variables, discrete probability distributions and some approximations. Furthermore, continuous probability distributions are studied, especially the normal distribution and statistical inference where confidence intervals for units and waiting values ??are calculated. The principle of hypothesis testing is clarified and applications leading to, among other things, chi-two tests are studied. In the class used spreadsheets for applications and calculations on statistical materials.
