Kinsey scale
The Kinsey scale, an approximate measure of sexual orientation, was used in the Kinsey Reports. The scale is as follows:
0- Exclusively heterosexual
1- Predominantly heterosexual, only incidentally homosexual
2- Predominantly heterosexual, but more than incidentally homosexual
3- Equally heterosexual and homosexual
4- Predominantly homosexual, but more than incidentally heterosexual
5- Predominantly homosexual, only incidentally heterosexual
6- Exclusively homosexual
