Expert writing Tips

Best practice

When using "arbitrary unit", clearly define what constitutes one unit within the specific context of your work. This avoids ambiguity and allows for meaningful comparisons within your dataset.

Common error

Avoid assuming readers know the scale or meaning of your "arbitrary unit". Always provide a reference or explanation so others can interpret your data accurately. For example, instead of just saying 'the intensity was measured in arbitrary units', specify 'the intensity was measured in arbitrary units, where 1 a.u. equals the fluorescence of the control sample'.

Linguistic Context

The phrase "arbitrary unit" functions as a noun phrase, typically used to describe a unit of measurement that is not standardized or defined by an established system. As shown in Ludwig, it's often found in scientific contexts where relative measurements are more important than absolute ones.
