Medical Statistics Made Easy [antikvár]

PREFACE This book is designed for healthcare students and professionals who need a basic knowledge of when common statistical terms are used and what they mean. Whether you love or hate statistics, you need to have some understanding of the subject if you want to critically appraise a paper. To do this, you do not need to know how to do a statistical analysis. What you do need is to know whether the right test has been used and how to interpret the resulting figures. This book does not assume that you have any prior statistical knowledge. However basic your mathematical or statistical knowledge, you will find that everything is clearly explained. A few readers will find some of the sections ridiculously simplistic, others will find some bafflingly difficult. The "smiley faces" grading will help you pick out concepts that suit your level of understanding. The "star" system is designed to help you pick out the most important concepts if you are short of time. This book is also produced for those who may be asked about statistics in an exam. Pick out the "exam tips" sections if you are in a hurry. You can test your understanding of what you have learnt by working through extracts from original papers in the "Statistics at work" section.
