Are straight guys better at math than gay guys? Are lesbians better than hetero females? The Add Health Study asked teens what grade they earned in math last term. A's were assigned a 4, B's a 3, C's a 2, and D's or lower a 1. Here are the means:

Straight males 2.60
Gay males 2.30*
Straight females 2.75
