The tasks in this book are designed to reflect the same system as a real statistics exam: five answers are provided, of which only one is correct (Single Choice). The question pool is divided into two chapters. The first covers the entire area of descriptive statistics, containing 180 questions of various types and formats. The second chapter focuses on inferential statistics, supplemented with some examples from probability theory. Special emphasis has been placed on understanding the methods, while the calculation of specific tests and their decisions has been intentionally set in the background. This section includes more than 100 questions of various types and formats as well. The book has been specifically designed as exam preparation material. Contents include: Introduction, Descriptive Statistics.
