The purpose of this study was to explore a group of non-dating pre-adolescents meaning of dating by investigating their reasons for engaging in this social behavior and their perception of those activities that constituted this role from their present frame of reference. (Author)

A brief, practical overview of "design effects" (DEFFs) is presented for users of the results of sample surveys. The overview is intended to help such users to determine how and when to use DEFFs and to compute them correctly. DEFFs are needed only for inferential statistics, not for descriptive statistics. When the selections for…

Three procedures for evaluating the sampling specificity of results are reviewed. These procedures are Tukey's jacknife technique, Efron's bootstrap technique, and cross-validation methods. The jacknife technique uses different subsamples derived from the original total data set to provide empirical estimates of the generalizability of effect…

The question of how high a response rate is needed in order for telephone surveys to obtain data that accurately represent the entire sample, was investigated via reevaluating results of three previously published studies and reporting on three 1989 studies for the first time. The three previous studies indicated that, if the sample…

A guide to survey research is presented for both novice and experienced researchers. Steps of the survey research process are covered: (1) planning the survey to determine the purpose of the study, collecting background information, designing the sample, and making a time line for completing the project; (2) questionnaire design, including the…

The method for questionnaire construction described in this paper makes it convenient to generate as many different forms for a questionnaire as there are respondents. The method is based on using the computer to produce the questionnaire forms themselves. In this way the items or subgroups of items of the questionnaire may be randomly ordered or…

In the present study Monte Carlo methods were employed to evaluate the degree to which canonical function and structure coefficients may be differentially sensitive to sampling error. Sampling error influences were investigated across variations in variable and sample (n) sizes, and across variations in average within-set correlation sizes and in…

There are two general methods of cross-validation: empirical estimation, and formula estimation. In choosing a specific cross-validation procedure, one should consider both costs (e.g., inefficient use of available data in estimating regression parameters) and benefits (e.g., accuracy in estimating population cross-validity). Empirical…

The present investigation developed power curves for two parametric and two nonparametric procedures for testing the equality of population variances. Both normal and non-normal distributions were considered for the two group design with equal and unequal sample frequencies. The results indicated that when population distributions differed only in…

This memorandum responds to a request from the House Subcommittee on Census and Population for information concering the planning for the 1990 Census. It identifies eleven major issues concerning the implementation of the 1990 Census: (1) determination of who shall be counted; (2) provision of data for apportionment and redistricting; (3)…

Through utilization of effective sampling procedures, libraries may obtain substantial savings in terms of data collection costs. (Author)

The study was designed to ascertain whether or not attitudes held by college students toward certain proposed social actions were significantly favorable or unfavorable and whether or not there was any relationship between social class designation and the attitude variables. (Editor)

The aim of these pages is to provide some perspective on Project Zero's recent work, updating earlier accounts which have appeared in the Journal of Aesthetic Education and elsewhere. (Author)
