Statistics is a set of scientifically based tools. When combined with expert judgment, they help you achieve a greater understanding of systems and processes, and make better decisions in the presence of uncertainty.

Statistics enable:

• Managers to focus on important problems
  
• Workers to be more productive
  
• Scientists and engineers to improve experimental results
  
• Managers to make better decisions

Statistics achieves improved results through:

• Design and analysis of experiments
• Exploratory tools to extract information from large, messy data sets
• Modeling of spatial variability
• Quantifying dependencies
• Quantifying risk
• Constructing estimates of uncertainty
