CV calculation examples with different levels of relative variability

Low relative variability

A dataset with low variability relative to its mean shows a small CV value. This indicates the data points tend to be close to the mean in relative terms.

Statistics:

  • CV: 9.8615%
  • Mean: 99.9491
  • Standard deviation: 9.8564

Medium relative variability

A dataset with moderate variability relative to its mean shows a medium CV value. This indicates a moderate level of spread compared to the mean value.

Statistics:

  • CV: 30.4886%
  • Mean: 49.9997
  • Standard deviation: 15.2442

High relative variability

A dataset with high variability relative to its mean shows a large CV value. This indicates the data points are widely spread out compared to the mean value.

Statistics:

  • CV: 61.0319%
  • Mean: 24.2124
  • Standard deviation: 14.7773
