This useful volume promises to be the salvation of those who  despite a distaste for math  need to use statistics in their work. Approaching the topic through logic and common sense rather than via complex mathematics  the author introduces the principle and applications of statistics  and teaches his reader to extract truth and draw valid conclusions from numerical data. An indispensable first chapter warns the reader on the ways he can be misled by numbers  and the ways in which numbers are used to misrepresent the truth (arithmetical errors  false percentages  fictitious precision  incomplete data  faulty comparisons  improper sampling  failure to allow for the effect of chance and misleading presentation). There follows a wealth of information on probability  sampling  averages and scatter  the design of investigations  significance tests  all presented in terms of specific  carefully worked out cases that make them both interesting and immediately understandable to the layman. The book is so entertaining  so eminently practical  that youll gain expertise in the laws of chance  probability formulae  sampling methods  calculating the arithmetic mean and standard deviation  finding the geometric and the logarithmic mean  constructing an effective experiment or investigation using statistics  and a wide range of tests determining significance (zM test  X2 text  runs test for randomness and a number of others) and scores of other important skills  in a form so palatable youll hardly realize how much you are learning  Scores of tables illustrate the text  and a complete table of squares and square roots is provided for your convenience. A handy guide to significance tests helps you to choose the test valid and appropriate for your data with speed and ease. Written with humor  clarity  and eminent good sense by a scientist of international reputation  this book is for anyone who wants to dispel the mystery of the numbers that pervade modern life  from news articles to literary criticism. For the biologist  sociologist  experimental psychologist or anyone whose profession requires the handling of a large mass of data  it will be of incalculable value.\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":45118246551605,"sku":"ByrdShop_0486227294","price":29.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8139\/0901\/files\/9780486227290.jpg?v=1781697256","url":"https:\/\/atxbooks.com\/products\/practical-statistics-simply-explained-dover-books-on-mathematics-9780486227290","provider":"ATX Books","version":"1.0","type":"link"}
