This study examined the reliability and validity of the scores of a Chinese-translated version of the Gifted Rating Scales-School Form (GRS-S) using parents as raters and explored the effects of gender and grade on the ratings. A total of 222 parents participated in the study and rated their child independently using the Chinese version of the…

This investigation reports on the cross-cultural equivalence testing of the Self-Description Questionnaire II (short version; SDQII-S) for Indigenous and non-Indigenous Australian secondary student samples. A variety of statistical analysis techniques were employed to assess the psychometric properties of the SDQII-S for both the Indigenous and…

Controversy over the proper place of significance testing within scientific methodology has continued for some time. The suggestion that effect sizes are more important than whether results are significant is presented. Effect size can be defined as an estimate of how much of the dependent variable is accounted for by the independent variables.…

Investigates two aspects of research analyses in quantitative research studies reported in the 1996 issues of "Journal of Counseling & Development" (JCD).

The Survey of Perceived Organizational Support (SPOS) is a unidimensional measure of the general belief held by an employee that the organization is committed to him or her, values his or her continued membership, and is generally concerned about the employee's well-being. In the interest of efficiency, researchers are often compelled to use a…

Statistical significance is often misinterpreted to mean replicability or generalizability of results, although a statistically significant difference does not equal a reliable difference. Sample splitting procedures may be a more accurate way of estimating research result generalizability. This type of cross-validation involves randomly dividing…

This study evaluates the reliability of self-assessment as a measure of computer competence. This evaluation is carried out in response to recent research which has employed self-reported ratings as the sole indicator of students' computer competence.

The degree to which reliability affects the power of analysis of variance (ANOVA) tests involving one factor with two and three samples was quantified and tabulated by taking into account sample size, level of significance, and true score effect size. Results confirm a substantial effect on power. (SLD)
