Prerequisites (in Czech)
Students should have some basic knowledge of statistics, i.e., ideally any previous Introduction to Statistics course. Students should be familiar with the following terms: sample, dataset, variable (continuous/ordinal/nominal; dependent/independent), research question, hypothesis testing, statistical significance, mean, mode, median, standard deviation, distribution.
Course Enrolment Limitations
The course is also offered to the students of the fields other than those the course is directly associated with.

Course objectives (in Czech)
The goal of this course is to teach students to perform basic descriptive and inferential statistical analyses. Students will learn to prepare a dataset, carry out essential statistical analyses using the SPSS software and interpret them. This course will be followed by E0430 in the spring semester, which will be focused on advanced methods of statistical analyses (SEM, HLM, analysis of longitudinal data).
Learning outcomes (in Czech)
At the end of the course the student will be able to:
-work with datasets - create datasets, transform variables, identify problematic cases, clean data
-use IBM SPSS Statistics for data handling and data analysis
-create SPSS syntax files that are reproducible
-understand, conduct, and interpret common statistical inferential tests in SPSS
-report the results in a proper format

Teaching methods (in Czech)
The teaching format is an in-person lecture supported by PowerPoint presentations followed by a practicum in the computer lab. Students will use IBM SPSS statistical software to perform statistical analyses discussed in the lectures.
Assessment methods (in Czech)
Students will complete a practical data analysis exercise during the practical session, and will be asked to submit it after each such session to receive attendance and activity points. Additionally, there will be three quizzes throughout the semester (multiple choice format). The quizzes will not be cumulative. Lastly, there will be no final exam. Instead, students will submit an assignment, which will consist of statistical analysis and its write-up using their own data or data provided by the instructors if necessary. There will be opportunities for earning extra credit throughout the semester.
The grading is broken down as follows:

Attendance and activity (15% of grade)
Quiz 1 (15% of grade)
Quiz 2 (15% of grade)
Quiz 3 (15% of grade)
Final assignment (40% of grade)

This corresponds to the following grades: A (100%-92%), B (91%-84%), C (83%-76%), D (75%-68%), E (67%-60%), F (< 60%).
