    Under usual circumstances we would not recommend Wikipedia as a resource because of the open source nature of the reference. However, we have found it may be a good place to start for descriptions for many statistical terms and it provides good links to other resources. This link is specific to the statistics section which gives a brief primer; the resources at the end are good too. Please be sure to check other references as well.
