DSST statistics

[clep3705]

You should follow the official objectives for any test, AP, CLEP, DSST, ECE, SAT, whatever. The objectives for a test are developed first. After that, item writers create test items based on the objectives. If the official DSST exam guide doesn't mention Poisson or anything that could be a proxy for it, then you don't need to know it. Tests match the objectives. Don't start looking for tricks. The Idiot's Guide is intended for people trying to learn statistics in general. It is not a DSST exam prep book. In other words, it covers things that aren't necessarily on the DSST exam.

You could take the test now to find out what you need to learn and retest in 90 days.
