Discovering Statistics Using R
Autor Andy Field, Jeremy Miles, Zoé Fielden Limba Engleză Paperback – 21 mar 2012
Evoluția recentă a analizei de date în mediul academic reflectă o migrare masivă către instrumente open-source, flexibile și dinamice. Discovering Statistics Using R surprinde exact acest moment, adaptând pedagogia celebră a lui Andy Field pentru limbajul R, un standard care devine indispensabil în științele sociale. Observăm că această lucrare nu este un simplu manual de codare, ci o reconstrucție a modului în care statistica poate fi predată fără a intimida studentul, păstrând rigoarea necesară cercetării contemporane.
Suntem de părere că forța acestui volum rezidă în structura sa narativă. Autorii ghidează cititorul prin mediul R, începând cu instalarea și utilizarea R Commander, pentru ca apoi să escaladeze natural către modele statistice complexe. Cuprinsul indică o progresie logică: de la „Ce naiba caut eu aici?” — o secțiune dedicată demistificării fricii de statistică — până la stăpânirea tehnicilor de tip MANOVA și a modelelor multinivel. Această abordare completează perspectiva oferită de Univariate, Bivariate, and Multivariate Statistics Using R, adăugând acea componentă de angajament emoțional și umor care lipsește deseori manualelor tehnice stricte.
În contextul operei sale, această carte reprezintă pilonul tehnic modern care transformă viziunea din Discovering Statistics Using IBM SPSS Statistics într-un format accesibil gratuit oricărui cercetător. Dacă în eseuri precum Encounterism Andy Field explorează interacțiunea umană în spații fizice, aici el analizează interacțiunea minții umane cu datele brute, folosind un ton ireverențios și exemple din viața reală care transformă învățarea într-o experiență memorabilă. Găsim în cele aproape 1000 de pagini un echilibru rar între teorie conceptuală și aplicație practică, susținut de sarcini de lucru și resurse digitale suplimentare.

De ce să citești această carte
Recomandăm această carte studenților și cercetătorilor care doresc să stăpânească limbajul R fără stresul unui manual arid. Cititorul câștigă nu doar competențe tehnice solide în modelarea datelor, ci și încrederea de a naviga prin analize complexe, totul într-un format interactiv și amuzant. Este resursa ideală pentru a transforma statistica dintr-o barieră curriculară într-un instrument de descoperire.
Despre autor
Andy Field este profesor de psihopatologie infantilă la Universitatea din Sussex și o figură de referință în educația statistică la nivel mondial. Cu o activitate prodigioasă ce include peste 80 de lucrări de cercetare și 17 cărți, Field a reușit să revoluționeze modul în care este predată statistica, primind numeroase distincții pentru calitatea actului didactic. Este editor fondator al Journal of Experimental Psychopathology și a activat în comitetele editoriale ale unor publicații prestigioase precum British Journal of Mathematical and Statistical Psychology. Expertiza sa în dezvoltarea emoțională a copiilor se reflectă în stilul empatic și plin de umor prin care explică cele mai dificile concepte matematice.
Descriere scurtă
The journey begins by explaining basic statistical and research concepts before a guided tour of the R software environment. Next you discover the importance of exploring and graphing data, before moving onto statistical tests that are the foundations of the rest of the book (for example correlation and regression). You will then stride confidently into intermediate level analyses such as ANOVA, before ending your journey with advanced techniques such as MANOVA and multilevel models. Although there is enough theory to help you gain the necessary conceptual understanding of what you're doing, the emphasis is on applying what you learn to playful and real-world examples that should make the experience more fun than you might expect.
Like its sister textbooks, Discovering Statistics Using R is written in an irreverent style and follows the same ground-breaking structure and pedagogical approach. The core material is augmented by a cast of characters to help the reader on their way, together with hundreds of examples, self-assessment tests to consolidate knowledge, and additional website material for those wanting to learn more.
Given this book's accessibility, fun spirit, and use of bizarre real-world research it should be essential for anyone wanting to learn about statistics using the freely-available R software.
Recenzii
Take, for example, the chapter on t-tests. The chapter explains how to compare the means of two groups from scratch. It explains the logic behind the tests, it explains how to do the tests in R with a complete worked example, which papers to read in the unlikely event you do need to go further, and it explains what you need to write in your practical report or paper. But it also goes further, and explains how t-tests and regression are related---and are really the same thing---as part of the general linear model. So this book offers not just the step-by-step guidance needed to complete a particular test, but it also offers the chance to reach the zen state of total statistical understanding.

Field's Discovering Statistics is popular with students for making a sometimes deemed inaccessible topic accessible, in a fun way. In Discovering Statistics Using R, the authors have managed to do this using a statistics package that is known to be powerful, but sometimes deemed just as inaccessible to the uninitiated, all the while staying true to Field's off-kilter approach.

Probably the wittiest and most amusing of the lot (no, really), this book takes yet another approach: it is 958 pages of R-based stats wisdom (plus online accoutrements)... A thoroughly engaging, expansive, thoughtful and complete guide to modern statistics. Self-deprecating stories lighten the tone, and the undergrad-orientated 'stupid faces' (Brian Haemorrhage, Jane Superbrain, Oliver Twisted, etc.) soon stop feeling like a gimmick, and help to break up the text with useful snippets of stats wisdom. It is very mch a student textbook but it is brilliant... Field et al. is the complete package.

"This work should be in the library of every institution where statistics is taught. It contains much more content than what is required for a beginning or advanced undergraduate course, but instructors for such courses would do well to consider this book; it is priced comparably to books which contain only basic material, and students who are fascinated by the subject may find the additional material a real bonus. The book would also be very good for self-study. Overall, an excellent resource."
The main strength of this book is that it presents a lot of information in an accessible, engaging and irreverent way. The style is informal with interesting excursions into the history of statistics and psychology. There is reference to research papers which illustrate the methods explained, and are also very entertaining. The authors manage to pull off the Herculean task of teaching statistics through the medium of R... All in all, an invaluable resource.
