В Oracle 11g как определяте средното тегло на данните на час между две дати?

Използвайки вашите примерни данни - нямаше данни за цял час, така че направих среднопретеглена стойност за минута.

Не сте посочили какво искате да правите на границите, така че взех среднопретеглената стойност на непосредствено предходните и следващите стойности.
