Problems encountered in univariate analysis of variance for repeated measures can be circumvented without recourse to less generally familiar multivariate methods. (Authors)

It is important to overall teaching effectiveness to shift the attention role back and forth." (Author)

A computational short cut suggested by Feldman and Klinger for the one-sided Fisher-Yates exact test is clarified and is extended to the calculation of probability values for certain two-sided tests when sample sizes are unequal. (Author)

The paper presents applications and methods of analysis for non-linear hyperbolic partial differential equations. The paper is concluded by an account of wave front analysis as applied to the piston problem of gas dynamics. (JG)

Considers a ball which is dropped from a height h above a flat surface and rebounds to a height rh, when r is a positive fraction less than one. The question asked is if the ball continues to fall and rebound in the same manner, how much time is required for the ball to come to rest? (RP)
