Best practice
When using "it fluctuated between", ensure the subject is clearly defined and the range of fluctuation is specific to avoid ambiguity. For example, specify units of measurement (e.g., "It fluctuated between 20 and 30 degrees Celsius").
Common error
Avoid stating only one endpoint of the fluctuation. Always provide both the upper and lower bounds to give a clear understanding of the extent of the variation. For instance, instead of saying "It fluctuated above 50", say "It fluctuated between 50 and 60".
