The standard approach of most introductory books for practical
statistics is that readers first learn the minimum mathematical
basics of statistics and rudimentary concepts of statistical
methodology. They then are given examples of analyses of data
obtained from natural and social phenomena so that they can grasp
practical definitions of statistical methods. Finally they go on to
acquaint themselves with statistical software for the PC and
analyze similar data to expand and deepen their understanding of
statistical methods. This book, however, takes a slightly different
approach, using simulation data instead of actual data to
illustrate the functions of statistical methods. Also, R programs
listed in the book help readers realize clearly how these methods
work to bring intrinsic values of data to the surface. R is free
software enabling users to handle vectors, matrices, data frames,
and so on. For example, when a statistical theory indicates that an
event happens with a 5 % probability, readers can confirm the fact
using R programs that this event actually occurs with roughly that
probability, by handling data generated by pseudo-random numbers.
Simulation gives readers populations with known backgrounds and the
nature of the population can be adjusted easily. This feature of
the simulation data helps provide a clear picture of statistical
methods painlessly. Most readers of introductory books of
statistics for practical purposes do not like complex mathematical
formulae, but they do not mind using a PC to produce various
numbers and graphs by handling a huge variety of numbers. If they
know the characteristics of these numbers beforehand, they treat
them with ease. Struggling with actual data should come later.
Conventional books on this topic frighten readers by presenting
unidentified data to them indiscriminately. This book provides a
new path to statistical concepts and practical skills in a readily
accessible manner. Â
