We'll, the idea is many schools may require some math faculty to teach some statistics courses, and so taking a stats courses may improve your odds of getting a position in a currently tough job market. Good idea. I'm taking dissertation credits and I still have 2 course requirements to fulfill. However, in the fall of 2016 and spring of 2017 (my projected graduation date) I'll have 3 credit hours free each semester. I'm primarily focused on getting a teaching and or research position, so the stats course may improve my marketability as a teacher. See my comment above.
