Expert writing Tips
Best practice
When referring to data, ensure grammatical accuracy by using "piece of data" or "data point" to indicate a singular item. Using "data" alone implies plurality.
Common error
Avoid treating "data" as a singular noun. Use "datum" for the singular form or rephrase to use "piece of data" or "data point" to maintain grammatical correctness.

Ludwig's WRAP-UP
In summary, while the phrase "except one data" is used to indicate an exception within a dataset, it is grammatically incorrect because "data" is generally treated as a plural noun in English. Ludwig AI confirms this. To maintain grammatical accuracy, it's better to use alternatives such as "except one "data point"" or "except one "piece of data"". The phrase is relatively rare and, while found in scientific and news-related contexts, should be avoided in formal writing to ensure correctness and clarity.
