Course Description:

This seminar provides an introduction to basic statistical concepts and techniques used for the collection, organization, analysis, and presentation of various types of laboratory data, including how to assess the relationship between two variables and methods for calculation and evaluation of measurement performance indicators in an environmental laboratory.

Expected Learning Outcomes:

  • Understand numerical and categorical types of data in the laboratory
  • Understand the terms population, batch, sample, sampling methods, and bias type and direction
  • Understand and be able to calculate relative error, relative standard error, %RSD, % recovery, control limits, and percent differences in calibration curves
  • Understand sample data distributions
  • Be able to use linear regression to create a least-squares line and calculate the correlation between two numerical variables in a data set
  • Understand and be able to perform hypothesis testing, outlier tests, and t-tests to show statistical differences between results
  • Significant figures and rounding
  • Be able to graphically represent and interpret laboratory data

Intended Audience:

This course is designed for Laboratory management (Laboratory Director/Technical Manager/Quality Assurance Manager), supervisors, and key laboratory staff.
