Research Methodology

Second Edition, January 2016 Revised 23 January 2017

See Contents

After a review of free statistics programs, and web sources for further study, the book begins by expanding on some of the basic concepts such data types and variables. Great emphasis is put on various easy ways of describing data. This must precede anything more sophisticated. The basic choice then is between the family of statistics which compares groups, and the family which studies associations or correlations. Only then, once these three major areas of statistics are mastered, students are ready for more detail in the choice of statistical test.

At this point the old statistics, with its emphasis on significance testing and the null hypothesis is presented, then thoroughly critiqued. The ‘New Statistics’ is presented. There is a detailed explanation of the base rate fallacy. Confidence intervals, Confidence levels, power, and effect size are explained.

This book is the only textbook for Second Language English speakers doing research. As such it is easy to read, thorough, and functions as the first book students need. It is based on over 20 years of teaching a course of 20-30 hours and has been extensively reviewed by hundreds of users. My students tell me the book has a little bit of everything, and touches many details completely missing from other textbooks. Science and Medical students writing a thesis in English (their second language) have also found it helpful.

New pdf book 12 July 2014 revised 15 July 2015 and 22 July 2016

Almost every book I have read on statistics is too difficult! This book bridges the gap.

Are you afraid of statistics? Do you find them hopelessly complicated? Then you have come to the right place: I agree with you! Here I present statistics for the ordinary person. Examples are taken from areas of ordinary life. Enjoy it! A feel for statistics begins with basic concepts behind the statistics and never gets harder than simple arithmetic. For far too long the mathematicians have confused us with complexity, whereas the real problems lie elsewhere. The course is presented as a series of key ideas. The absolute starting point is Key one - definitions. If these are not agreed upon, bye-bye statistics.

In Keys 10-16 the whole subject of ‘controls’ is discussed. Very few textbooks explain this and many people find it difficult. This is partly because ‘controls’ is in fact a cluster of concepts and by breaking it down, all is made clear.

Teaching time is about 10 hours.
