Having students gather their own statistics is promoted. The BEADS program provides an alternative; it simulated sampling from a binomial distribution. Illustrations from the program are included. (MNS)

The Guide is a list of favorably reviewed microcomputer software, based on critical evaluations conducted by participating organizations. Programs are listed by content (arithmetic, advanced mathematics, geometry and measurement, algebra). Title, publisher, computer used, level, and mode of instruction are included in the table. (MNS)

This column is designed to share BASIC sub-programs and to show how subroutines and function subprograms may be used to simplify and organize BASIC programing. The yes-no function is defined and programs presented, followed by the multiple-branch function and adding a HELP feature. (MNS)

Presented are simple programs in BASIC and FORTRAN to apply the method of least squares. They calculate gradients and intercepts and express errors as standard deviations. An introduction of undergraduate students to such programs in a chemistry class is reviewed, and issues instructors should be aware of are noted. (MP)
