If you were in a cafeteria full of students and you wanted to randomly divide 10 students into group A and 10 students into group B, what would be the least biased way to do it?

Specifically for a two sample t test on difference in means with a matchedpairs design. What would the stepbystep process be for a simple random sample from the cafeteria population?

Which do you want, a random sample or matched pairs?
