When the CV is below 20%, what does this tell me about my data?

The standard deviation is less than one-fifth of the mean.

20% has no special meaning and we are assuming that this variable is always positive. A small CV simply means that the data in not very viable. Also, since CV is dimensionless, it is easy to compare variables.

I meant to say that a small CV means that the data is not very variable - has a small variability in comparison with the mean .
