Deaf persons, in their communications, use verbal and non-verbal communication systems, as well as bilingual communication. The aim of this article is to determine which communication system the deaf people prefer, and to determine whether there is a statistically significant difference between the sub-samples of the respondents in the preference of the communication systems using discriminant analysis. Study findings have shown that deaf people prefer a non-verbal communication system and a bilingual manner of communicating, and do not reject the verbal communication system because it is essential to communicating with hearers but, they do not prefer it. Discriminant analysis revealed that there was no statistically significant difference between the sub-groups of the respondents at a statistical significance level of 0.01.
