text: Depending on the school, you may just need to take one math class (usually called something like Math for Lib Ed majors).  It encompasses the basics of several different types of math.  However, depending on how far you want to go in Psychology, they may also have you take a Statistics class.  In fact, if you can, I would advise taking the Statistics class over the Lib Ed Math class - the Statistics class could provide you with some useful information that you may actually use later in life, but it's generally thought of as being a little harder.  Most people I know, though, struggle with advanced math because they see the problem and think "how on earth is doing this problem going to help me later in life?"  It's hard to work up the motivation to learn something if you can't see the point in learning it, right?  Well, while you may not ever use the Pythagoream Theorem again after Lib Ed Math, many of the concepts in Statistcs can be applied to situations you run into every day.  Good luck!
