Informationen zum Autor John Townend is the author of Practical Statistics for Environmental and Biological Scientists, published by Wiley. Klappentext Studenten und Forscher in Umwelt- und Biowissenschaften müssen bei ihrer Arbeit mitunter auf statistische Methoden zurückgreifen. "Practical Statistics for Environmental and Biological Scientists" ist eine präzise, verständlich geschriebene und benutzerfreundliche Einführung in die Statistik, die überflüssigen Fachjargon vermeidet. Behandelt wird die Planung und der Entwurf von Experimenten, die Datenanalyse und -präsentation sowie Möglichkeiten und Grenzen der jeweiligen statistischen Methoden. Der Autor erläutert detailliert, wie Tests durchgeführt und Ergebnisse interpretiert werden und geht dabei von den Methoden aus, wie sie von den gebräuchlichsten Softwarepaketen, wie Excel, MINITAB und SPSS angeboten werden. Die Anwendung von Formeln wird auf ein Minimum beschränkt. Mit einer Fülle nützlicher Beispiele und einer Literaturliste zu jedem Kapitel. Zusammenfassung All students and researchers in environmental and biological sciences require statistical methods at some stage of their work. Many have a preconception that statistics are difficult and unpleasant and find that the textbooks available are difficult to understand.
