Course objectives
The main objective of the course is to introduce statistics as a part of psychology and the elementary statistical concepts used in psychological research. Students will learn to passively and actively use these concepts. They learn to prepare data for analysis, compute elementary statistics, test elementary hypotheses. They also learn to read and communicate statistical findings both in Czech and English.
Learning outcomes
Student who successfully passes the course will be able: - to arrange data in conventional data matrix; to compute basic descriptive statistics describing the distribution of individual variables and relationships among them; to draw graphs describing the distribution of individual variables and relationships among them; to compute confidence intervals for basic descriptive statistics; to test elementary hypotheses; to use linear regression with one predictor; to use conditional probabilities to compute the indices of diagnostic utility of tests.
Syllabus
• 1. Data matrix, types of variables, coding, measurement levels, data checking.
• 2. Graphical representation of data. Cumulative, absolute and relative frequencies and distribution. Tables, minimum, maximum, outliers. Normal distribution and areas under the curve. Bar chart, histogram.
• 3. Measures of central tendency and variability, percentiles, standard scores. Boxplot.
• 4. Measures of association (Pearson, Spearmann, Kendall) and graphical representation of relationship. Scatterplot. Linear, positive, negative association. Partial and part correlation.
• 5. Linear regression. Statistical prediction, linear vs. non-linear regression. Estimate, model, residual. Least squares method. Regression and residual variance, susms of squares. Coefficient of determination. Homoscedascity.
• 6. Probability, conditional probability, probability distributions. Bayes' theorem, indices of diagnostic utility.
• 7. Statistical inference, point vs. interval estimates. Statistics vs parameters. Sampling distribution, standard error. Central limit theorem.
• 8. Statistical hypothesis testing, Bayesian, Fisherian and Neymann-Pearson approach. Level of significance, Type I and II error, power, effect size, t-tests, tests for Pearson correlations.

Assessment methods
Midterm exams
There are three very short midterm exams. Each is worth 10 points. Their dates are listed in the interactive template. The number of points earned from the three midterms is computed according to the following Excel formula =ROUND((SUM(P1;P2;P3)-MIN(P1;P2;P3))*1,5;0). This formula takes the best two results and scales them back to 30. This allows for one bad result or even absence. It is generally not possible to re-take the tests at a later date.
Team assignemt
There is a team-work assignment worth 10 points.

Final exam
The final exam is a paper-and-pencil test with a personal calculator worth 50 points. To pass the exam the student must earn at least 30 points. The test covers all materials listed in this syllabus and in the imteractive template.
