If you’ve found this page, it’s because you’ve bought and read “The simple way to understand research methods and statistics in psychology” and you’ve seen the offer to get the cost of that book deducted from your purchase of “How to Study Psychology.”
Unfortunately, that offer is no longer available. Apologies for that – the book moved to print in 2012 and I had to stop selling the electronic version, which that offer applied to.
Apologies!
