Statistics in steps

Statistics in Steps by Nel Verhoeven
ISBN: 9789024434510
Publication Date: 2020
The methodology described in Statistics in Steps makes statistics comprehensible for students and lecturers. This textbook gives a clear and concise explanation of how certain statistical techniques work and what they are used for, illustrated by real-life examples. The book focuses on how statistical techniques are used, not on the formulas behind them (although they are treated in the book as well). Thus enabling students to use statistics as a useful tool to process quantitative data.
