This report summarizes all of the primary statistical modeling and analysis results
associated with the Ca Poly Pomona Topsoil Lead Contamination study. The purpose of
this report is to document both the implemented sampling design and all corresponding
data modeling and inference techniques used during the subsequent statistical analyses.
Additionally, this report is designed to serve as a template for describing the sampling
protocol and statistical analysis techniques in any future technical manuscripts developed
by the client(s).
The remainder of this report is organized as follows. Section 2 describes the
development of the sampling protocol, including both the initial recommended design
and final implemented sampling strategy. Section 3 presents the basic univariate
statistics that summarize the contamination data associated with the seven analyzed
metals (for all 360 topsoil samples)Section 4 presents the analysis of the sampling
depth effect, based on the 43 sites where topsoil samples were acquired from two
sampling depths. Section 5 next describes the two types of exploratory data analysis
(EDA) plots used for initially determining the degree of spatial structure present in the
metal concentration data; i.e., the quatile maps and robust variogram plots.
