The results of this research have relevance for sport educators who are integrating sport classes and who are concerned with the interpersonal interactions of boys and girls playing together. The author hypothesized that males and females would prefer to interact in a sport setting with members of their own sex and ability level. The results of an analysis of variance indicated that: (1) males generally preferred to interact with males; (2) females did not generally tend to differentiate on the basis of sex; (3) low ability subjects were equally willing to interact with low or average ability others; and (4) average ability males were equally willing to play with average or above average players while average ability females preferred to interact with similar others.
