Forensic Analysis - QA5

These flashcards cover key vocabulary terms related to laboratory proficiency and analytical chemistry as discussed in the lecture.

Bias Assessment

Evaluating the systematic error in laboratory measurements to ensure accuracy.

Certified Reference Materials (CRM)

Highly controlled materials used to calibrate instruments and validate methods.

Proficiency Testing Schemes

Organized programs to evaluate a laboratory’s ability to perform tests accurately against a standard.

Inter-laboratory Testing

Testing of similar samples by multiple laboratories to assess consistency and performance.

Laboratory Performance Evaluation

Assessment of a laboratory's efficiency and accuracy through systematic review.

Precision Assessment

The evaluation of the closeness of repeated measurements to each other.

Robust Statistics

Statistical methods that are less sensitive to outliers in data analysis.

Z-score

A measure that describes a value's relation to the mean of a group of values; used to evaluate bias performance.

P-score

A performance measure used to assess precision relative to the target standard deviation.

Statistical Outliers

Observations that are significantly different from the majority of data points, influencing statistical analysis.

Quality Assurance (QA)

Procedures to ensure that the laboratory processes meet defined standards.

Homogeneous Samples

Samples that have a consistent composition throughout, crucial for accuracy in testing.
