Different sources of assessment evidence are reviewed during International Baccalaureate (IB) grade awarding to convert marks into grades and ensure fair results for students. Qualitative and quantitative evidence are analysed to determine grade boundaries, with statistical evidence weighed against examiner judgement and teachers' feedback on…

'QuantCrit' (Quantitative Critical Race Theory) is a rapidly developing approach that seeks to challenge and improve the use of statistical data in social research by applying the insights of Critical Race Theory. As originally formulated, QuantCrit rests on five principles; 1) the centrality of racism; 2) numbers are not neutral; 3) categories…

Publication bias is the disproportionate representation of studies with large effects and statistically significant findings in the published research literature. If publication bias occurs in single-case research design studies on applied behavior-analytic (ABA) interventions, it can result in inflated estimates of ABA intervention effects. We…

There is a longstanding and pressing challenge regarding overuse of exclusionary discipline (e.g., office discipline referrals, suspensions) for students of color and students with disabilities. Moreover, many common efforts to address the problem have not been shown to enhance equity in school discipline. This article describes a promising…

A robust finding in social psychology is that people judge negative events as less likely to happen to themselves than to the average person, a behavior interpreted as showing that people are "unrealistically optimistic" in their judgments of risk concerning future life events. However, we demonstrate how unbiased responses can result in data…

This revenue study is based on Fiscal Year 2010-11 (FY11) data for each of 30 selected states plus the District of Columbia (D.C.). Traditional school districts and public charter schools were analyzed and aggregated "statewide." For each state, one to three "focus areas" were selected based on larger concentrations of charter…

Avoiding statistical mistakes is important for educators at all levels. Basic concepts will help you to avoid making mistakes using statistics and to look at data with a critical eye. Statistical data is used at educational institutions for many purposes. It can be used to support budget requests, changes in educational philosophy, changes to…

Article focused on the reasons for the under employment of women and the myths that persist in spite of indisputable evidence to the contrary. (Author/RK)

A comparison of different tracking methods used to locate respondents is presented. (PS)

The major objective of this paper was to demonstrate that it is possible, using a probabilistic approach, to derive a method of evaluating the interaction of adverse effect, criterion differences, and bias and, using a linear model, determining their effect on job relatedness. (Author)

Substantial changes were found to have occurred in the age distribution and evaluation team experience of institutional accreditation team visitors and chairpersons employed between 1970 and 1977. Criticisms such as "clubiness," duplication of effort, and preference for or dominance of certain types of institutions are discussed. (Author/LBH)

Distortion and selective disclosure limit data that are available to program evaluators, producing a bias that tends to maintain the status quo. Paradoxically, attempts to objectify the data only increase the potential for distortion. Ironically, one way to encourage innovation may be to not measure it. Additional solutions are suggested.…

A research study is reported which investigated the influence of the variables of race (examiner and child race) and expectancy (high and low) upon the scoring of individual IQ tests. Video tapes of two children (one black, one white, 10 years old, in the 85 to 95 IQ range) being administered the Wischler Intelligence Scale for Children were shown…

The perception of bicultural stress, stress due to discrimination/prejudice, immigration, and acculturation, was investigated in relation to mental well-being in a sample of urban Latino (n = 304), European American (n = 215), and Asian American (n = 131) 8th grade students. Bicultural stress was reported by all ethnic groups and was significantly…

First-year veterinary medicine students were surveyed during the first and last week of class to determine if student ratings of instructors are free of bias from generalized attitudes. The tabulated results indicate that the students were not biased by preconceived opinions of instructors. (BH)
