Expert writing Tips

Best practice

When comparing experimental results, always clearly identify and describe your "untreated sample" to establish a clear baseline for assessing the effects of treatments.

Common error

Don't assume the "untreated sample" is completely inert or devoid of the characteristic you're measuring. Always analyze and report its initial state to provide context for subsequent treatment effects.

Linguistic Context

The phrase "untreated sample" functions as a noun phrase, where "untreated" is an adjective modifying the noun "sample". It is typically used to identify a subject in a scientific experiment that has not been subjected to any manipulation, serving as a baseline for comparison. According to Ludwig, this phrase is correct and usable in written English.
