Use of Practical Statistics in Site Investigations and Risk Assessments (May 16 & 18th)
May 16 @ 9:00 AM - May 18 @ 9:00 AM UTC-8
Once we have completed the site investigation, we have to make sense of the data obtained. Dr. Dennis Helsel will guide you through practical approaches and tools for a statistical analysis of your data.
Following areas will be covered:
- Goal for statistical methods
- The mean and UCL95
- The geometric mean and the median
- The 90th and other percentiles
- One population or two?
- Weighting observations unequally
- Comparison of existing data to background concentrations
- Dealing with outliers
