The primary objective of the series is to provide critical reviews of research problem areas and techniques, the content of state-of-the-art conferences, and integrative research reviews. Its dual publication emphasis is rapid and targeted dissemination...

A Simple Method for Evaluating the Cleaning Power of Commercial Detergents

Commercial detergents, in spite of their various names and marks, are used to remove foreign matter (dirt) from substrate. Following removal of dirt from the surface, it is necessary to prevent redeposition, so the detergent must have supending power. In this experimental work, a simple method has been developed to evaluate the cleaning power of commercial detergents. The method, showing th...

A Method for Evaluating Physical Activity Programs in Schools

Providing opportunities for students to be physically active during the school day leads to increased academic performance, better focus, and fewer behavioral problems. As schools begin to incorporate more physical activity programming into the school day, evaluators need methods to measure how much physical activity students are being offered through this programming. Because classroom-based p...

A Simple Transformation Method in Skewness Reduction

Statistical analysis of non-normal data is usually more complicated than that for normaldistribution. In this paper, a simple root/power transformation technique developed by Niaki, et al [1]is extended to transform right and left skewed distributions to nearly normal. The value of theroot/power is explored such that the skewness of the transformed data becomes almost zero with anacceptable err...
