The use of computer spreadsheet programs in the physics laboratory is discussed. An example of this application with a conservation of energy laboratory is presented including the cases of a rolling sphere and a sliding sphere. (CW)

Presented is an experiment where the concentrations of three metal ions in a solution are simultaneously determined by ultraviolet-vis spectroscopy. Availability of the computer program used for statistically analyzing data using a multivariate linear regression is listed. (KR)

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)

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)

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)

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)

Presented is an approach to introducing upper division, undergraduate geology students to nonparametric statistics and their application to geologic data. Discussed are the use of the Mann-Whitney U and the Kolmogorov-Smirnov tests and a class assignment which illustrates their use. (CW)

Discussed are experiments that may be done using a microcomputer to analyze scattering data. Apparatus assembly, procedures, and results for this activity are presented. (CW)

Discussed are problems encountered when a gas absorption experiment with strong measurement error is used. Notes students either avoid the experiment or report it as defective. Provides ideas to make lab experiments more instructive. (MVL)
