Although intended for A and AS Level studentsfollowing a course in statistics,
first year or university students who are either meeting statistics for the first time
or who require a refresher course, would find that this book contains useful
support material.
How to Use this Book
The topics included in Work Out Statistics A-Level cover the syllabuses of all
examining boards at A-Level in the subject. In particular, your attention is
drawn to chapter 15 which has been included to cover those areas which are
examined but are often not contained in textbooks. The chapter headings follow
the systematic order offered by most contemporary textbooks. Most topics
contain worked solutions of past paper questions from examining boards. As
different boards and papers take the subject to varyinglevels,so some topic areas
will prove to be quite difficult. Such topics and worked examples have been
marked with an asterisk (*) and you need not work through these sections if they
are not givenparticular emphasis on your syllabus.

Revision
The course you are following will normally be a subset of the contents of this
book.It is therefore important to know yoursyllabus. (Syllabuses and past papers
can be obtained from the examination boards listed on pp.ix-x). Once you have
eliminated the chapters/topics which you do not require, revise a topic at a time
trying the appropriate worked examples and then comparing your answer with
the worked solution. The exercises at the end ofeach chapter have been carefully
chosen to cover fully the subject area in that chapter, so try to answer as many of
these as possible before referring to the answers at the back ofthe book. Included
in the answer section are some hints on the solution ofeach exercise; these should
help you to understand where you are going wrong if your answer is different
from the one given by the authors.
Most numerical solutions in this book have been worked using four-figure
accuracy. Slight numerical differences may exist between your answers if you
have worked to a higher degree of accuracy. However, the authors feel that for
examination questions whichareto take lessthan 30 minutes each, a higher degree
of accuracy is time consuming and unnecessary for the purpose of solving the
problem.
It is important that you should familiarise yourself with the statistical tables
that you are to use during the examination as they may vary from one examina
tion board to another.
Remember to start your revision in good time and use this book as a positive
aid to the active and thorough knowledge ofyour statistics course.
