YOUDEN diagram of a ring trial for serum cortisol the virtual dot in the middle of the diagram represents the IDMS target values for sample A and B and the squares demonstrate the limits of acceptance left

Youden plot has been drawn in to indicate the spread of values.

Youden plot of a natural and a MeHg spiked raw extract of fish The results obtained by each laboratory for sample A and B are reported on the horizontal and the vertical axis respectively. The intersection of both results is figured by the points in the graph. Dotted lines of the central square show the standard deviation of the mean of means. In an ideal case all laboratories should have their results in the square. Some sets of results are far from this point which demonstrates the presence of remaining systematic errors in these methods. Results far from the line show random errors.

Youden plot of aluminium data for samples X and Y

Youden plot of the determination of Al in marine sediments expressed as z-scores. The plot shows clear systematic differences due to the method of sample digestion. The group of lower group used an HF treatment or non-destructive methods e.g. XRF.

Youden plot of the determination of Cd in marine sediments, expressed as z-scores. The results show a mixture of both random and systematic errors. Most data are within Z 2.
