Statistical Analysis

As the field of environmental problem solving has matured, statistical approaches have become more fully integrated into a variety of decision types, including sampling, risk assessment, and trend analysis. This page presents a diverse group of DSTs that help the user solve a variety of common problems in environmental investigation and remediation; however, each of these tools exemplifies how a DST can support a decision or action by providing a statistical underpinning to the decision-making process.
