Figure 2 : Inter-rater reliability for the manual assessment of steady-state gaite speed and cadence during a single trial of a 6-Minute Walk Test.

Each data point represents the average of 10 raters for that lap, while the error bars represent one standard deviation from the mean. Note the narrow scaling for gait speed and cadence for the purpose of magnifying inter-rater differences.
