Statistics blur minority distinctiveness.
In their study of the success of drug treatment, Sirotnik and Roffe blurred and probably minimized racial and ethnic distinctions. Their problem was trying to compare Whites, Blacks, and Chicanos with a statistic requiring two-art or scalar variables. Of non-Blacks (compared to Blacks), 29% were Chicanos, and of non-Browns (compared to Chicanos), 32% were Blacks. Nonetheless, of nine variables significantly associated with "staying in treatment," five were blackness, brownness, or synonymous with them. A format with only percentages would enable analysis to see substantive results clearly and in more detail.
