Significance Testing: Parametric and Nonparametric

A statistical significance coefficient is the chance that a relationship as strong or stronger than the one observed was due to the chance of random sampling. Thus if a correlation coefficient is significant at exactly the .05 level, this means there is 5% chance that a correlation as strong or stronger than the observed one would result from an unusual random sampling of data when in fact the correlation was zero. There are many, many specific significance tests. Common tests are listed below, but in addition each statistical procedure has associated significance tests which are discussed in the respective Statistical Associates "Blue Book" volumes dealing with each procedure.

The full content is now available from Statistical Associates Publishers: http://www.statisticalassociates.com.

Currently I am teaching in Med. School, at San Carlos University, Guatemala. This course is for Associate and Professors, They don't need all the theory and formulas, they need to know how to do the analysis of their data, and all the variants they have. So this book is very useful for this purpose. In general this book can be used for any kind of postgraduate course
