Easily explain key concepts of statistics like the complicated confidence intervals. It is similarly good for teaching statistics and for empowering research in the disciplines that deal with data analysis like meteorology, mathematics, and the like.

Instat+ is a general statistical package. It is simple enough to be useful in teaching statistical ideas, yet has the power to assist research in any discipline that requires the analysis of data.
Instat+ provides a relatively gentle introduction to using statistics packages, and can be a useful "stepping-stone" towards other, commercial, statistics packages.
Instat+ is designed to support the teaching of statistics. It includes features to help explain many of the key concepts, such as confidence intervals, that users often find confusing. Furthermore, its teaching menu provides a resource pack of ideas, some that use Instat, but many that can be used with any statistical software.
Instat+ includes many special facilities for the processing of climatic data, supported by a 400 page guide, included with the package as a help file. These facilities have formed the basis of numerous agroclimatology training courses, in the UK, Kenya, Niger, Algeria, Syria, the Philippines and elsewhere.
