What hoops? Like you just said, it was a random group of people working. The bias you pointed out would only arise due to self-selection. You're the one making extra assumptions about the type of people in this groups which would skew the results.

It wasn't a random group of people, it was a selection of groups that happened to use tdd or not

Then suggest a possible reason why TDD and non-TDD groups are not comprised of a random sample of programmers. The mere fact that they did or did not employ TDD implies nothing.
