{"product_id":"9783662667859","title":"Understanding Inferential Statistics : From A for Significance Test to Z for Confidence Interval by Markus Janczyk","description":"What actually is a p-value for? And what is a significant result? This book answers such questions by providing a compact introduction to inferential statistics. Our major focus is on the logic of inferential statistics and hypothesis testing: We cover the logic behind statistical tests, we then walk through the most common procedures (t-test, analysis of variance with and without repeated measures, correlation\/regression) and discuss pitfalls of data analysis. The book thus helps developing a solid understanding of how common test procedures work, and how to interpret their results correctly. Hands-on examples from everyday research - including exemplary calculations with the programs SPSS and R - supplement each chapter. In addition to classical methods, we briefly discuss recent developments in psychological research methods.   This book is a translation of the original German 3rd edition of \"Inferenzstatistik Verstehen\" by Markus Janczyk and Roland Pfister. It is based on an AI-powered machine translation (by the service DeepL.com), with thorough follow-up editing by both authors.\u003cbr\u003eBinding: Paperback \/ softback","brand":"Gardners","offers":[{"title":"Default Title","offer_id":56310885319029,"sku":"9783662667859","price":19.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/7193\/3106\/files\/9783662667859.jpg?v=1762815662","url":"https:\/\/backstory.london\/products\/9783662667859","provider":"Backstory","version":"1.0","type":"link"}
