Instructor: Dr. Paul Hewett Ph.D. CIH
Course description:
This 2.5 hour webinar PDC consists of Part I of a two part introduction to
Industrial Hygiene Statistics (IH Statistics). IH Statistics refers to those
statistical methods and concepts that have proved useful for characterizing
occupational exposure data and for IH decision making.
(See the list of Prerequisites.)
Part I covers the statistical methods used to estimate the parameters of
the exposure profile (i.e., distribution of exposures). Included is an introduction
to the normal, z-value, and lognormal distributions; distribution parameters
vs. sample statistics; goodness-of-fit testing; descriptive statistics; compliance
statistics (percentiles and exceedance fractions); confidence intervals and
hypothesis testing; and non-parametric statistics.
The webinar will last 2.5 hours, with an additional 30 minutes for followup
questions and clarifications. Each student must, within 2 weeks of the seminar,
complete a 20 question test that (the test will require approximately 30 to
60 minutes). In addition, the students are encouraged to read the suggested
references prior to the webinar. A certificate and 0.5 CM points will be awarded
to those students that both attend the webinar and complete the 20 question
test.
Learning Objectives:
(1) Ability to calculate and interpret both descriptive and compliance statistics.
(2) Ability to calculate and interpret confidence intervals for the most commonly
used compliance statistics.
(3) Ability to use both subjective and objective goodness-of-fit procedures
to validate the use of the lognormal distribution model.
(4) Appreciation of the relationships between exposure data, sample statistics,
and IH decision making.
(5) Awareness of the major issues, pitfalls, and problems associated with
the analysis and interpretation of occupational exposure data.
