Google's Conversion University is actually focused on teaching people how to use Google Analytics to track visitor behavior on their site, not conversions per se. Unlike some training offerings, Google tries to give some context to the measures and how to interpret them. That sort of thing can help analysts figure out how measures found in Google Analytics might relate to conversions.

But, measures alone don't tell the whole conversion story.

You need to relate these measures to goals, and getting to goals is the hardest part for most organizations where the web site has typically been done as a feature to be checked off a checklist. A key part of the initial work in our conversion course involves coming to terms with what the goals must be for each landing page.

That bluster aside, Google's Conversion University is the best resource I've seen for getting down the basics of Analytics, and we're using it to that end.
