1 Introduction
Background
The Sampling Design Software (SDS, Version 2.0) was developed as a
companion to the Instruction Report "Sampling Design for Reservoir
Quality Investigations" (Gaugush 1987). Four programs were de-
veloped to assist the user with problems with sampling design and its eval-
uation. The programs aid the decision-making process in sampling design
through the use of decision matrices (the DECMATRX program). Sampling
design evaluation is performed
variance component analysis (the
VARCOM program), error analysis (the ERROR program), and cluster
I
analysis (the CLUSTER program).
The purpose of this user's manual and the SDS disk provided with it is
to assist the user in the implementation of these programs and is not in-
tended to provide instruction on the assumptions and calculation methods
of the statistical techniques used by these programs. The Bibliography
presents a number of sources for basic statistics, sampling design, and
more advanced statistical topics. The instruction report mentioned pre-
viously represents
introduction to the topic of sampling design. An in-
troduction to statistics from a reservoir water quality perspective can be
found in "Statistical Methods for Reservoir Water Quality Investigations"
1986).
Contents of the SDS Disk
A total of 39 files are provided on the SDS disk. The
files are
the compiled program files for DECMATRX, VARCOM; ERROR, and
CLUSTER. These programs were developed and compiled using Turbo
Pascal 5.5 (Borland International, Copyright 1984, 1989). The program
files also have associated help files (files with an extension of
Three example data sets are provided for the programs VARCOM,
ERROR, and CLUSTER. These data sets are EG.VAR, EG.ERR, and
EG.CLS, respectively.
