Oil analysis is when the oil is tested for contaminants/deposits and and conditions that vary against it's original qualities. (paraphrasing in a major way).
By testing for heavy metals like zinc, silver, copper and so on and testing for contaminants like fuel, carbon, acid and so on, not only the condition of the oil itself can be scored, but the wear conditions of the machine the oil came form as well...

GT is correct, and you are not a Dummy, you just have not yet been informed.
Oil analysis in short hand is a test that checks for wear activity, physical properties, and oil condition. In a basic oil analysis test you are checking for:
1. Abnormal wear in your engine, for example in your pistons, bearings, etc.
2. Intrusions from coolant, water, or dirt
3. The overall condition of the oil, is it lubricating properly, is it time to change the oil, etc.
