The test consisted of a multiple-choice questionnaire in which the examinee was asked to identify the meaning of 100 words as they were then used in black ghettos.
[1] Examples of words used included alley apple, black draught, blood, boogie jugie, and boot.
[1] The original sample used in the experiment consisted of 100 white and 100 black St. Louis high school students, aged 16–18 years old – half of them being from low socioeconomic levels and the other half from middle income levels.
In the other samples the results were similar with the black students' scores being drastically different from those of the whites.
The results of these tests and examination of the BITCH-100 confirmed Robert Williams' belief that his intelligence test dealt with content material that was familiar to blacks.
