- S. G. Carmer,
- W. M. Walker and
- R. D. Seif2
A two-part rule is given as a practical guide in preliminary tests of significance for determining whether or not otpool two or more variances for use as “error term” in subsequent F tests for treatment effects. Four examples involving commonly occuring analysis of variance tables are given to illustrate the use of the rule.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
