A Dictionary of Statistics for Psychologists

Psychologists need to know about statistics but they can easily get bogged down in unfamiliar jargon. This new dictionary is an invaluable reference for all undergraduate and postgraduate students of psychology. It provides definitions of the statistical terms most commonly encountered in psychological literature. It explains simply and clearly what the methods/topics are and how to apply them, and in many cases, some mathematical details and a numerical example follow a brief written account of a term. In addition, graphical material help make definitions clearer. This unique approach makes this dictionary an essential purchase for all students grappling with increasingly sophisticated statistical methods in their data analysis. Preface vii
