The problem of comparing proportions when some data are missing is investigated, and determination is made of what statistical techniques are appropriate under each of several probability models describing the observations likely to be missing. Monte Carlo methods were used to investigate the properties of standard estimators under each of the…

Thirty-three Parent-Child Centers (PCCs) are grouped into five clusters according to thematic orientation of content or intent for parents' and children's programs in order to provide models which may be viewed as strata in selecting Centers as sampling points for Phase II of the national PCC evaluation--an in-depth study of project impact on…

This study was designed to examine the effectiveness of social reinforcement as a function of familiarity with the adult agent administering the reinforcers. First and fifth grade children were tested in a marble dropping task on two successive days. On the second day half of the children at each grade level were tested by the same experimenter…

Interest in quantifying nonverbal variables in human interaction has led to the development and application of several nonverbal observation systems. The authors present a selective overview of these approaches, briefly explaining the major assumptions in terms of their differences and similarities. Drawing largely from their own experiences in…

It was hypothesized that unstable subject-item interactions on personality scales would be associated with small psychological distances between subjects and items. It was further hypothesized that this relationship would be more demonstrable when the psychological test was more homogeneous. To clarify the rationale of the first hypothesis, an…

The field test of using task data for recruitment of horticulture workers is the final phase of a larger task analysis study of the ornamental horticulture industry in New York State.

AN ANALYSIS OF DATA COLLECTED FROM STUDENT REGISTRATION CARDS AND THE FORMULATION OF A STUDENT QUESTIONNAIRE CONSTITUTE THE FIRST PART OF A THREE-STAGE LONG-RANGE RESEARCH PROJECT TO EVALUATE A UNIVERSITY CORRESPONDENCE STUDY PROGRAM. THE DATA ANALYSIS DESCRIBES THE POPULATION OF CORRESPONDENCE STUDENTS IN TERMS OF RELEVANT INDIVIDUAL AND SOCIAL…

The National Food and Agriculture Council of the Philippines regularly requires rapid feedback data for analysis, which will assist in monitoring programs to improve and increase the production of selected crops by small scale farmers. Since many other development programs in various subject matter areas also require similar statistical…

Activities to date are summarized for the California Education Information System (CEIS), a data processing service which provides county and regional offices with a series of automated applications capable of meeting the majority of standard pupil and business information processing requirements. The following components are included: an outline…

This paper attempts to provide some insight into the reality of data analysis and interpretation. Community college institutional researchers should obtain the skills and techniques required in order to analyze and interpret data; however, there are a number of practical considerations usually not found in textbooks. These include: (1)…

A general decision-theory analysis of the word-frequency effect in recognition memory is carried out. On the basis of the analysis and data from a forced-choice experiment two distinct causes of the frequency effect are defined. (Editor)
