Laboratory statistics

Understand SD, CV, standard error and confidence intervals.

Explore the topic
Synthetic distributions showing how standard error decreases with sample size while the spread of individual results stays the same.

Learn by exploring

Spread and precision:
see the difference.

Use the illustrated statistics guide to distinguish the spread of individual results from the precision of an estimated mean.

Original figures and worked examples use synthetic data.

Practical guides to start with

Clear explanations, worked examples and next steps.

COMPARE

Do two methods agree?

A strong correlation can hide clinically important differences. Inspect agreement across the measuring interval.

Explore the guide

INTERPRET

What does a good EQA result tell me?

Separate peer-group agreement from agreement with a reference target.

Explore the guide

ESTIMATE

Build a defensible top-down estimate

Use routine performance data intelligently and avoid double counting.
