The average Q Score for a female star on primetime TV is 21. So not only is Perrette beloved by more than twice the percentage of Americans who identify her average contemporary as being among their faves, she blows away the closest female competitor.

Here are the eight women who line up behind Perrette and Henson, all of whom rate well above average in Positive Q Scores:
