Co-efficient of variation.
Thus, statistically the headway data can be described as exponential if the co-efficient of variation is unity.
Precision was confirmed by measuring the co-efficient of variation (CV) of repeated measurements taken in 2h periods.

Genetic characterization of grain Zn in several Recombinant Inbred Lines (RILs) and also in rice germplasm collections has shown significant Phenotypic Co-efficient of Variation (PCV), Genotypic Co-efficient of Variation (GCV), broad-sense Heritability and Genetic Advance (GA) (Table 1).
A study on urban roads of Riyadh reported that usually such co-efficient of variation falls in the range of 0.5 to less than 1.5 corresponding to the flows that range between 500 and 2000 vph [4].
However, research on heterogeneity effect into traffic flows indicates that co-efficient of variation is likely to deviate under such traffic mostly because of complicated traffic flow dynamics, thereby, making exponential model inappropriate in describing headways.
The fundamental statistical properties of the headway data such as mean, median, standard deviation, co-efficient of variation were examined at different volume to capacity ratio and presented in Table 3.
Statistically, the headway data can be described as exponential if the co-efficient of variation is unity resulting in an exact 450 plot of mean and standard deviation [4, 5].
Repeatability was assessed using the limits of agreement which were best between trials 2 and 3 where the distance cycled was -0.54 km below and 1.34 km above the distance cycled for trial 2. The co-efficient of variation (CV) for distance for three trials was 3.58%.
Horses that moved least during sonographic inspections had the lowest co-efficients of variation.
