(TI59) 2way ANoVA & Duncans multirange test
An excerpt from A Program for TwoWay ANOVA & DUNCAN'S New MultipleRange Test On a Small, Programmable Calculator, Insecticide and Acaricide Tests 7:2, NCSU  Entomology Dept., 3 pages
" Nelson (I & A Tests, 1:49) explained the importance of the role of statistics in Insecticide and Acaricide Tests. Since then, statistical analysis of data included in the reports has become the rule rather than the exception. C. W. Averre's (I & A Tests, 2:710) contribution of a program for a twoway analysis of variance on a Texas Instrument SR52 calculator was instrumental in this increase. Since his publication, the SR52 has been replaced by the Tl programmable 59. The TI59 is similar to the SR52 in that programs can e stored on magnetic cards. However, the TI59 has the capacity to program up to 960 steps (compared with the SR52'S 223) and solid state software library modules are available that can be inserted in the back of the calculator. The TI59 lists for $237.50 but is available from many sources for under $200. The modules list for $40. the same printer used with the SR52 may be used with the TI59. The program below uses one magnetic card and the Applied Statistics Module. It is designed to be used with the PC100 printer and includes the following features: transformations, data conversions, actual and transformed data mean printout, printout of degrees of freedom (i.e. error, treatments, and replicates), probability of a greater F value, and Least Significant Range values, one advantage of this program is that it needs to be entered only once into the calculator to run any number of analyses on different data sets. However, the program is limited to an experimental design having a sum total number of treatments and replicates less than 16. The advantage of this program is its portability, allowing data analysis away from the office. It is inexpensive, and more expedient than using computers in large computer centers. Operation time for a complete analysis of data from an experiment with four replicates and sixeight treatments is approximately ten minutes, including data input. " BEST! SlideRule
