I thought about taking a statistics primer/refresher before I start my graduate PM degree this Fall. Does the below certification seem legit to all of you? There may be some free courses all there. I only want to take what will be helpful and do not want a bunch of fluff. Business Statistics Course - $99.99, ExpertRating Online Business Statistics Certification
If you are not looking for credit their is a college course on video here Resource: Against All Odds: Inside Statistics
Another option if you are not looking for credit, is to buy a Statistics for Dummies book. You can buy them used on Amazon.com for under $10 and those books are usually quite good. The name may be insulting, but the information is always concise and very well put together. I've used these books for refreshers in accounting and finance.
