Intelligence of college women as related to family size.

Abstract

Randolph-Macon Woman's College 'Estimate based upon the freshmen class who entered the college in 1944. The mean age of this group was 17.8 with an SO of 0.42.

Intelligence and family size.

“…Since the correlations in question are generally quite low, the operation of selective factors, however slight, may produce a completely spurious result. An example of such a subtle selective factor is given in Shuey's study of students in an American women's college (85). Within the entire group of 2,261 entering students for whom test scores were available, a significant inverse relation was found between test scores and number of siblings.…”

“…A number of studies on college students, in both Great Britain and the United States, have yielded very low and usually insignificant correlations between intelligence test scores and number of siblings (39, 64,65,85,102,103). This lack of correlation is understandable in the light of the highly selected nature of such samples.…”
