Four cases which illustrate statistical factors in complexation reactions (where two of the reactants are monodentate ligands) are presented. Included are tables showing statistical factors for the reactions of: (1) square-planar complexes; (2) tetrahedral complexes; and (3) octahedral complexes. (JN)

Nonlinear least squares computer programs are extremely valuable in fitting complicated equations to experimental data. They are easy to use and free students and teachers from the tedium of trying to derive linearized forms to complicated equations. The use of these programs (available for most medium/large scale computers) is discussed. (JN)

Describes an attempt to plot the walking speeds of crowds as a Maxwellian velocity distribution in one dimension, analagous to an ideal gas approximation. (CP)

Identifies and explains some of the crucial elements of team research and data analysis, points out common pitfalls, and makes some helpful suggestions. Sections include general recommendations and communicating in statistical language. (ZWH)

Describes how the statistical technique of meta-analysis can be used to help resolve conflicting studies in social sciences. (ZWH)

Described are analytical applications of the theory of random processes, in particular solutions obtained by using statistical procedures known as Monte Carlo techniques. Supercomputer simulations, sampling, integration, ensemble, annealing, and explicit simulation are discussed. (CW)

Describes laboratory exercises with chickens selecting their food from dyed and natural corn kernels as a method of demonstrating natural selection. The procedure is based on the fact that organisms that blend into their surroundings escape predation. (BR)

Describes a project in which fingerprint patterns were identified and analyzed to determine whether any positive relationship existed between pattern type and academic ability. (LS)

A meta-analysis of studies of the impact of new science curricula on the performance of students was initially conducted in 1983 as part of a coordinated program of meta-analysis of research on science education. This paper reports the results of a re-synthesis of the research dealing with student performance in the new science curriculum using…

Presented are common words and phrases which are encountered in the statistical analysis of test results. Included are analysis of the mid-point, distribution of scores, calculation of scaled scores, test reliability, item analysis, and coefficients of reliability. (CS)

Reviewed are the basic concepts of experimental design, analysis of data, and optimization. Discussed are two-level factorial designs; fractional factorial designs and blocking, additive, linear, and quadratic models; quadratic and composite designs; and designing experiments in design. (CW)

Methods for meta-analysis have evolved dramatically since Gene Glass first proposed the term in 1976. Since that time statistical and nonstatistical aspects of methodology for meta-analysis have been developing at a steady pace. This guide is an attempt to provide a practical introduction to rigorous procedures in the meta-analysis of social…

Described are teaching methods used to teach measures of central tendency to middle and high school students. Discussed are quantitative and qualitative data, basic experimental terms, a general overview of data analysis, data charts for quantitative data, qualitative data analysis, and extensions for older students. (CW)

Offers teachers a useful alternative to research methods of the natural science. Using an example of teacher-based action research in the classroom, the author helps to describe the purpose and most efficient execution of this method of research. Also discussed is the issue of validity and reliability. (ZWH)

A model of Brownian motion is discussed which includes viscosity effects. The model lends itself to Monte Carlo simulation and thus is suitable for an elementary physics laboratory experiment. (BB)
