I'd agree in regard to the math level of graduate education students but based on a limited sample. I got my Masters in Public Health and took a few graduate classes in the Statistics & Research Methods dept with people who were getting Masters degrees in Education.
When I took the GRE it had three sections: math, verbal, and analytical. I got a nearly perfect score on analytical, close to that on verbal and high on math but not near perfect. In other words, I'm above average in math but not fantastic at it. I clearly recall one of the stats classes where all of the people in the class save for me and one other person couldn't seem to understand the concept of doing the parts of the equation that were within the parenthesis first (PEMDAS -- order of operations). I and the other person who got it spent nearly the entire period going around helping the other students figure out where they needed to start on some rather simple equations.
These people were nearly all Masters in Education students.
