Sample size and statistical power are important factors to consider when planning a research synthesis. Power analysis methods have been developed for fixed effect or random effects models, but until recently these methods were limited to simple data structures with a single, independent effect per study. Recent work has provided power…

The popularity of online surveys has increased the prominence of using weights that capture units' probabilities of inclusion for claims of representativeness. Yet, much uncertainty remains regarding how these weights should be employed in analysis of survey experiments: Should they be used or ignored? If they are used, which estimators are…

In educational research, characteristics of the learning environment (e.g., social climate, instructional quality, goal orientation) are often assessed via student reports, and their associations with outcome variables such as school achievement or student motivation then tested. However, studying the effects of the learning environment presents a…

Using instructional variables identified by the literature as important in predicting classroom achievement, a bi-polar rating scale was designed to assess the structure of instruction in resource rooms. The data for 158 elementary school children in four school districts were analyzed. The scale evidenced good reliability, both in terms of…

This report provides preliminary technical information on a method for analyzing the factors involved in the closing of elementary schools. Included is a presentation of data and a brief discussion bearing on descriptive statistics, reliability, and validity. An intercorrelation matrix is also examined. The method employs 9 factors that have a…

The predictive relation between neonatal behavior and temperament at 24 months was examined for 67 infants selected from the full socioeconomic status (SES) distribution. Initial ratings were made when the infants were one to four days old. Irritable neonates were rated as more upset, less attentive to stimuli, and less responsive to the staff at…

To investigate the causes of variation in cloze-comprehension test correlations, a reanalysis was conducted of the influential J.R. Bormuth study (1962), which reported correlations between nine cloze and nine comprehension tests administered to 50 subjects in grades 4, 5, and 6. Two separate renalayses were completed in the present study, the…

Texts on measurement theory report many studies on the consistency of intelligence test scores, but the stability of academic achievement over the school years has never been adequately studied. To investigate the stability of achievement test scores from fourth grade to college, a random sample of 100 students was selected from a 1978 graduating…

Examined the accuracy and validity of self-reports and their effect on tests of attitude-behavior relationships. Self-reports were reasonably accurate, but they produced results different from actual behavior in attitude-behavior tests. Concludes that self-reports and actual behavior should be measured, tested, and modeled separately. (Author/LS)

Greek parents (N=320) were given the Child Abuse Potential (CAP) Inventory and results were compared with American scores. Internal consistency reliability was high for four scales (abuse, distress, rigidity, and inconsistency). The Greek and American versions had similar factorial structures. Comparison found that Greek scores were significantly…

A 12-item acculturation scale developed for Hispanics correlated highly with the respondents' generation, length of residence in the United States, age at arrival, ethnic self-identification, and with an acculturation scale. Language use, media preferences, and ethnic social relations were the three factors accounting for 67.6 percent of the total…

Addresses the validity of the Cognitive-Affective Response Test-Music by clarifying the theoretical assertions on which the construct validity of the instrument rests. Presents nine specific assertions and data from two studies. Concludes that the test is valid for college-bound high school students. (CFR)

Uses the various strategies involved in baseball to illustrate basic concepts in game theory. Specifically discusses Willie Mays' base-stealing strategy and how it relates to probability and risk. Reminds students that expected results depend on adopted assumptions. (MJP)

This study was an examination of the usefulness of a statistical regression approach to identify prospective Engineering and Information and Computer Science (ICS) applicants most likely to succeed at the University of California at Irvine (UCI). The specific purpose was to determine the extent to which preadmissions measures such as high school…

A study was conducted to determine if a teacher-constructed cloze procedure correlated significantly with two standardized tests of reading achievement, thereby testing G.D. Spache's claim that most teachers are unable to design valid and reliable assessment materials. Subjects were 60 fourth and sixth grade students who were administered the…
