This reading material and the associated exercises provide a review of very basic statistics for use by students who plan to study economics in graduate school or who have long ago completed their graduate study and need a quick review of the basics of what they have learned. The material consists of a document in PDF form and many Excel spreadsheet files together with a few Gnumeric spreadsheet files which are identical to the corresponding Excel files except that they contain graphs that Gnumeric can read.
