أيهما أشد خطراً، المسدس أم حوض السباحة؟ ما هي الأشياء المشتركة بين معلمي المدارس ومصارعي السومو؟ لماذا ما يزال تجار المخدرات يعيشون مع أمهاتهم؟ ما هو مقدار اهتمام الوالدين حقاً؟ ما هو تأثير قضية «رو» و«ويد» في جرائم العنف؟ قد لا تبدو هذه الأسئلة مثل الأسئلة النمطية التي يسألها الاقتصادي، لكن ستيفن د. ليفيت ليس اقتصادياً نمطياً؛ إنه عالم شجاع أكثر من أي شيء آخر، يدرس المادة والأحاجي في الحياة اليومية ــ من الغش والجريمة إلى الرياضة وتربية الأطفال ــ وتقوم استنتاجاته عادة على قلب الحكمة التقليدية رأساً على عقب. وغالباً ما يبدأ بتل كبير من المعطيات وبسؤال بسيط لم يطرح من قبل. إنه يهتم ببعض هذه الأسئلة مثل قضايا الحياة والموت، وبعضها الآخر ذو ميزات استثنائية دون شك. وهكذا يحتوي هذا الكتاب على حقل جديد من الدراسة، وهو (الاقتصاد العجيب). ومن خلال سرده للقصص الآسرة ومن النظرة العميقة غير المباشرة، يبين ليفيت وزميله ستيفن ج. دوبنر أن الاقتصاد -في جذوره- دراسة للحوافز ـــ كيف يحصل الناس على ما يريدون أو يحتاجون، لاسيما عندما يريد الناس الآخرون الشيء ذاته أو يحتاجونه. في كتابهما (الاقتصاد العجيب)، يشرع المؤلفان في استكشاف الجانب الخفي ـــ من كل شيء؛ الأعمال الداخلية لعصابة مخدرات، وحقيقة الوسطاء العقاريين، وأساطير تمويل الحملات. وقصص الغش لدى معلمي المدارس. وأسرار جمعية كوكلوكس كلان (العرقية). ومن هنا فإذا كانت الأخلاق تمثل كيف نريد للعالم أن يسير، فإن الاقتصاد يمثل كيف يعمل العالم فعلاً. صحيح إن قراء هذا الكتاب سيتسلحون بقصص وأحاجٍ تكفي لتروى في آلاف الحفلات، لكن كتاب (الاقتصاد العجيب) يستطيع أن يقدم أكثر من ذلك، إنه يعيد تعريف الطريقة التي ننظر بها إلى العالم الحديث تعريفاً حرفياً. العبيكان للنشر

Permutation Statistical Methods

This research monograph provides a synthesis of a number of statistical tests and measures, which, at first consideration, appear disjoint and unrelated. Numerous comparisons of permutation and classical statistical methods are presented, and the two methods are compared via probability values and, where appropriate, measures of effect size. Permutation statistical methods, compared to classical statistical methods, do not rely on theoretical distributions, avoid the usual assumptions of normality and homogeneity of variance, and depend only on the data at hand. This text takes a unique approach to explaining statistics by integrating a large variety of statistical methods, and establishing the rigor of a topic that to many may seem to be a nascent field in statistics. This topic is new in that it took modern computing power to make permutation methods available to people working in the mainstream of research. lly-informed="" audience,="" and="" can="" also="" easily="" serve="" as="" textbook="" in="" graduate="" course="" departments="" such="" statistics,="" psychology,="" or="" biology.="" particular,="" the="" audience="" for="" book="" is="" teachers="" of="" practicing="" statisticians,="" applied="" quantitative="" students="" fields="" medical="" research,="" epidemiology,="" public="" health,="" biology.

Statistics Explained is a reader-friendly introduction to experimental design and statistics for undergraduate students in the life sciences, particularly those who do not have a strong mathematical background. Hypothesis testing and experimental design are discussed first. Statistical tests are then explained using pictorial examples and a minimum of formulae. This class-tested approach, along with a well-structured set of diagnostic tables will give students the confidence to choose an appropriate test with which to analyse their own data sets. Presented in a lively and straight-forward manner, Statistics Explained will give readers the depth and background necessary to proceed to more advanced texts and applications. It will therefore be essential reading for all bioscience undergraduates, and will serve as a useful refresher course for more advanced students.

An imaginative introduction to statistics, reorienting the course towards an understanding of statistical thinking and its meaning and use in daily life and work. Gudmund Iversen and Mary Gergen bring their years of experience and insight into teaching the subject, incorporating such innovations and insights as a sustained emphasis on the process of statistical analysis and what statistics can and cannot do as well as careful exposition of the ideas of developing statistical and graphical literacy. In the spirit of contemporary pedagogy and by using technology, the authors break down the traditional barriers of statistical formulas and lengthy computations encountered by students without strong quantitative skills. Further, formulas are grouped at the end of each chapter along with related problems, and, with only algebra as a prerequisite, the book is ideal for students in the liberal arts and the behavioural and social sciences.
