The term "creative" is commonly used in everyday language and in academic discourse to discuss the nature of artistic and innovative productions. This usage inherently implies the existence of a variable of creativity that allows different creative works to be compared. The standard definition of creativity asserts that a production must…

Studies based on longitudinal data focus on the change and development of the situation being investigated and allow for examining cases regarding education, individual development, cultural change, and socioeconomic improvement in time. However, as these studies require taking repeated measures in different time periods, they may include various…

This manual provides guidance and documentation for users of the longitudinal kindergarten-fourth grade (K-4) data file of the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011). It mainly provides information specific to the fourth-grade round of data collection. The first chapter provides an overview of the…

This manual provides guidance and documentation for users of the longitudinal kindergarten-fourth grade (K-4) public-use data file of the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011), which includes the first release of the public version of the third-grade data. This manual mainly provides information specific…

Describes the appropriate control of experiment-wise error rates and the researcher's role in making decisions to control for Type 1 errors. Issues related to level of significance, one- versus two-tailed tests, and the use of multivariate statistics are included. (Author/CT)

This paper compares an uncorrected with a corrected correlation between a selection test and a test-criterion in terms of expected mean square error (EMSE). It presents evidence that although the uncorrected may be more biased than the corrected correlation, it may have a smaller EMSE value, especially in small samples. (Author/PN)

This review of issues about correcting for attenuation concludes that the basic difficulty lies in being able to identify and equate sources of variance in estimates of validity and reliability. Recommendations are proposed for cautious use of correction for attenuation. (Author/CM)

The utility of combining confirmatory factor analysis and second-order methods is illustrated in a study of responses of 487 undergraduate and graduate students to the love instrument of C. Hendrick and S. Hendrick. Second-order confirmatory methods allow the researcher to explore complex realities more thoroughly. (SLD)

Assesses the reliability and stability of television exposure, and the relationship of various demographic variables to this hypothetical construct, when measurement error is removed. Analyzes data collected from Black adults. Concludes that more attention should be given to theoretically defining media exposure and to taking into account…

Drawing from work on the meta-analysis of over 500 validation studies of the General Aptitude Test Battery (GATB) by the U.S. Employment Service, the paper presents a methodological message and a substantive message. Gene Glass's methods, as used by Edwin Ghiselli in personnel selection, ignore study artifacts (sampling error, error of…

In this study, retrospective interviews were used to investigate reliability (and thus validity) threats to a computerized ESL listening comprehension test administered at a university in the US. The participants in the investigation, six international graduate students, were asked to respond to semi- and open-ended questions during individual…
