“There’s a lot of data that shows when there’s one woman on the board, it’s much more likely that there will be a second woman on the board.”

What was she trying to say? There can only be a second woman on a board when there is already a first: there are no boards with a second woman and no first woman. Is she trying to say that boards with two or more women outnumber boards with only one? I'll overlook the incorrect use of 'is' with the plural 'data', but I really would prefer some clarity about the basic meaning of her sentence.
(Before you accuse me of nit-picking and missing the point of the terrible crime of making a joke, let me point out I seem to be the only one listening to what she said and trying to understand it!)
