Effectiveness of Oversampling Blacks and Hispanics in the NHES Field Test. National Household Education Survey Technical Report.
Mohadjer, Leyla; West, Jerry
The National Household Education Survey (NHES) was conducted for the first time in 1991 as a way to collect data on the early childhood education experiences of young children and participation in adult education. Because the NHES methodology is relatively new, field tests were necessary. A large field test of approximately 15,000 households was conducted during the fall of 1989 to examine several methodological issues. This report describes the approach used to increase the number of Black and Hispanic American households and youth in the sample. During the field test, an approach that uses demographic information at the telephone exchange level to develop sampling strata was used to oversample Black and Hispanic American households. The yield of the field test sample design was compared to that which would have been expected without oversampling, and the effects of oversampling on the precision of survey estimates are reported. Oversampling did improve the precision of estimates of characteristics of Blacks and Hispanic Americans. Precision losses for overall totals and for non-Black and non-Hispanic American estimates are the price paid in order to improve the reliability of the estimates for Blacks and Hispanic Americans. Two tables and two figures report study data, and two appendixes contain screening ratios used to locate households of various groups and expected and observed sample sizes. (SLD)
