The seasonal biological surveys of 1971 / John C. Ayers, Samuel C. Mozley, John A. Stewart.

Treatment of the data in this report has been descriptive and intuitive,
i.e., no attempt is made here to apply statistical tests to the conclusions
about pattern or differences. This is because the sampling design by which
the data were obtained was based on the expectation that detailed statistical
analysis would not be necessary. We now recognize that a more careful, statistical approach to analysis is needed, and have been engaged in alterations
of design and procedure since 1972. The plan for statistical treatment of
1970-71 data has been presented in Part XVIII of this series (Johnston 1973).
A preliminary discussion of alterations in sampling design and analysis which
were begun in 1972 has already been presented (Mozley 1973a).
