Could somebody remind me of the explanation for y bar dot dot?

The dot notation means a normal summation over the letter that's replaced.

So y dot dot means we have summed over the i's and j's - that is we've summed everything.

Don't need y bar dot dot for SS calculations. But this would be the overall sample mean for all values.
