According to Bethesda's hint book, increased attributes have a starting range of 50 to 70 while decreased attributes have a starting range of 30 to 50. A normal range is 40 to 60. Remember that you can roll the dice as many times as you like and you get bonus points to add to your attributes (translation: don't take these too seriously).
