(SR-52) Statistical Tests

[SlideRule]

An excerpt from Small Programmable Calculators for Computing Statistical Tests, Insecticide and Acaricide Tests, Volume 2

     A large proportion of the field experiments reported in Insecticide and Acaricide Tests are simple and involve only
a dozen or so treatments with three to six replications (usually four) in a randomized complete blocks design. Results
are reported as insects observed and crop response. For this type of field experiment the "least significant difference"
(L.S.D.) and Duncan's New Multiple Range tests are, within certain limitations, well suited and widely accepted as aids
in evaluating results and making conclusions …

     In the last few years small, portable, electronic calculators with very sophisticated capabilities have become
readily available at very reasonable prices. We have found the TI SR-52 (Texas Instrument, Inc., Dallas, Texas) very
useful for analyzing our field plot data. It is a hand held calculator that has the capacity to program 223 steps which
can be stored on magnetic cards for future use …
