What to 'sample' in my writing?

[cappuccino336]

For writing samples, what is it that faculty want to see the most? For example, my senior thesis is well above most application maximums, so I'm going to have to choose a section or two at best to display my research and writing abilities/fit. With 20-25 pages, I could focus on my introductions and lit reviews, or I could also focus on methods and findings. I suppose I could cut and paste together something that 'samples' each section a little, but that seems weird. Thoughts?

YMMV, but if I were applying again, I'd showcase anything that involved original research, and maybe condense the lit review down as background. Have others weigh in, though! (And obviously check through the FAQs on school websites to see if schools have their own preferences.)

I would definitely show off something that demonstrates original research or the capacity to develop a well-grounded research project. For example, a well-edited (single authored) class research paper or, what I'm submitting, is my Master's thesis proposal.
