RESEARCH METHOD COHEN ok

2 INTRODUCTION
Package for the Social Sciences (SPSS) is the
most widely used statistical package in the
social sciences).
Additionally there are copious web site references
in nearly every chapter, most of which provide
free online materials. A signal feature of this
edition is the inclusion of several worked examples,
particularly in the chapters on data analysis in the
new Part Five.
To accompany this volume, a companion web
site provides a comprehensive range of materials
to cover all aspects of research (including a full
course on research methods on PowerPoint slides),
exercises and examples, explanatory material
and further notes, SPSS data files and SPSS
manual for novice researchers, QSR data files and
manual for qualitative data treatment, together
with further statistics and statistical tables.
(Qualitative Solutions and Research (QSR)
is a company which had produced software
such as N-Vivo for qualitative data analysis.)
These are indicated in the book. A wealth
of supporting materials is available on the
web site.
We have refined the referencing, relocating
several backup references to the Notes, thereby
indicating in the main text the most prominent
sources and key issues.
We hope that this volume will continue to
constitute the first port of call for educational
researchers.
