<p>In <a href="https://stats.stackexchange.com/questions/67159/paired-t-test-or-independent-t-test">Paired t-test or Independent t-test</a> @Damien asks about paired vs. independent t-tests. Two commenters have asked him to say more, but I don't see how he can, given his level of evident confusion. I think it would be OK to answer this with some hints, but I don't want to violate site policy.</p>

<p>Thoughts?</p>
