This is a straightforward and practical introduction to statistics for students without any advanced knowledge of mathematics who need to use statistical techniques. The author provides a wide selection of effective tools of the trade so that the reader can tackle a whole variety of concrete situations. No attempt is made to give a comprehensive account of the subject. Enough technique is explained so that the reader can appreciate when there is a need to turn to more advanced material elsewhere. The basic mathematics required is at the level of senior secondary school education, although even less is necessary for the earlier chapters of the book.
