And a second source we will visit often,
HyperStats
will give you another introductory section to review.
Here is a link that reviews "TYPES OF DATA" and has a set of MC questions to help you know your A-ready. The "next page" links at this site sometimes do not work. When that happens go back to the contents page and select the next topic. Worth the trouble..
Yet another good introductory link with brief explanations of many topics is at Statsoft page. Click on the top right link for the introductory material.
And to be sure you are really ready, there
are some multiple choice questions at Surf Stat from Australia.
