Chapter 11

Quality assurance and quality control (QA/QC)


Explain the terms accuracy, precision and robustness and how are they exactly determined?

Why is lower precision and a higher accuracy more acceptable than a lower accuracy with higher precision?

Why can complex environmental samples interfere with bioassays compared to pure chemicals?

What are the differences between mean deviation and standard deviation?

Explain the three different levels of replication which are required for comprehensive QA/QC.
