G6: Statistical Cage Match: 70 Percent vs. 95 Percent Confidence

Greater Columbus Convention Center 

Room: B 230 

CM Credit Hours: 1 

Best practices for modern IH programs include the use of statistical tools in the analysis of exposure data for a good reason. We know that without statistical tools, our professional judgment can often be wrong. Many organizations using statistical tools target a 95% confidence level ensuring that the 95th percentile of similar exposure group data remains below occupational exposure limits. However, other organizations as well as the EN689 standard have recommended a 70% confidence level. This presentation will: a) explain what these statistical confidence levels mean in practical terms; b) discuss the pros and cons of different levels of statistical confidence; and c) provide practical recommendations with respect to when and how to apply and interpret these confidence levels.

Upon completion, the participant will be able to:

• Calculate 70% and 95% upper confidence limits for IH data sets.
• Choose between 70% and 95% confidence with an understanding of the limitations of each.
