Data Analysis Calm

In addition to my research on the role of attitudes and motivation in second language acquisition, I have taught the graduate course in research design and statistics in the Department of Psychology since 1961 (see Curriculum Vitae for details). In 1990, I developed an undergraduate course on computer applications in psychological research and began writing chapters that could be used as the textbook. In 2001, my book titled “Psychological Statistics Using SPSS for Windows” was published by Prentice Hall, Upper Saddle River, NJ. This book was subsequently translated into Spanish and published by Prentice Hall as “Estadística para Psicología Usando SPSS para Windows” in 2003. The book was intended for undergraduate students and researchers who wanted an easy to read source for a number of statistical procedures used in research. In 2007, a colleague of mine and I revised it slightly, upgrading the SPSS applications to SPSS14 and adding two chapters. The reference for the coil ring book, which is now produced and sold by The Book store at the University of Western Ontario, London, Canada. is:

Gardner, R.C. & Tremblay, P.F. (2007). Essentials of Data analysis: Statistics and Computer Applications

I refer to this web page as DataAnalysisDot Calm because it contains a collection of unpublished manuscripts I wrote in the last few years to explain issues associated with data analysis as well as to provide examples of how to perform specific analyses. It also contains 19 power point lectures (in PDF form) that we used in the 2007/08 course in Research Design. The intent behind these materials is comparable to that underlying the preparation of the undergraduate book, viz., to provide an easy to read source on issues of interest to researchers.
