I think any reasonable approach realises that anecdotal evidence needs weighing appropriately. In the sibling comment for example if you merely wanted to establish if there are any incidences of children with "social awkwardness" that are home-educated (or if for example this is a product of a particular method of schooling) then you've got your tentative result off the bat. The fact that there are some such results allows you to hone your null-hypothesis and tune your approach to getting statistically significant data.

Anyway, I digress, anon.
