Statistical analysis underlies much of the modern scientific research. In fact, it is not too much of a stretch to say that many scientific fields have come of age and many other fields have become "scientific" thanks to the extensive use of statistics that they employ. The turning point seems to have been the advent of modern computer. For the first time in history the raw computational power has not been an issue any more, and the only limits on the quality of research became the amount of data that can be collected and the understanding of statistical methods that need to be employed for analysis.
This very short introduction deals with statistics as a method for analyzing empirical data. As such, it does not present statistics as a dry and self-contained mathematical subject. All the statistical methods are introduced in conjunction with particular practical problems that those methods are developed to address. The author, David Hand, is trying to convey the message that statistics is as much of an art as it is a rigorous mathematical method. No two research projects are the same, so no simple statistical procedure could be used to describe them all. A careful analysis of the problem at hand and a judicial choice of statistical methods are the most likely to yield the most useful information.
The book is divided in seven chapters and each one deals with a particular statistical concept or a particular way in which the statistics is used. The chapters are short but informative, and the whole book makes for one smooth read. It will not overburden you with mathematical detail, and it can be used as a springboard for further reading into the field of statistics.

Every day, we suffer a barrage of warnings about the threat of terrorism, war and apocalypse. The news is a parade of horrors. Anxiety is the stuff of daily life. And yet the statistics say we are the safest and healthiest humans who ever lived. How is this possible?
In this ground-breaking new book, Dan Gardner explains how we perceive risk, and examines the psychology that drives our fears. Analysing our risk perception as the combination of the brain's two simultaneous responses -- the intuitive feeling and the rational, considered response -- he throws light on our paranoia about paedophiles, chemical contamination, and suicide bombs, and explains why the significant threats to our lives are actually the mundane risks we pay little attention to.
Speaking to psychologists, economists, and scientists, Gardner reveals not only how we make judgments but how those judgments are influenced by corporations, politicians, activists and the media -- all of which have an interest in promoting irrational fear. In doing so, he explains one of the central puzzles of our time: Why are the safest and healthiest people in history living in a culture of fear?See also: The Science of Fear

Darwin's theory that man's ancestors were apes caused an uproar within the scientific world, as well as public frenzy when The Origin of Species was published in 1859.
Arguments still rage about the implications of his evolutionary theory, and skepticism about the value of Darwin's contribution to knowledge is widespread. In this analysis of Darwin's major insights and arguments, Jonathan Howard reasserts the importance of Darwin's work for the development of modern biology. He offers a stimulating view of the famous scientist in a concise, handy format, making it a masterpiece for all Darwinians as well as for all general readers of popular science.
