Definition of “Data”
The term “data” refers to facts, statistics, or pieces of information, often numerical, that are collected and analyzed. It can be used as a basis for reasoning, discussion, or calculation.
Understanding the nuances of its usage requires exploring its etymology, grammatical classification, and function within sentences.
Etymology
The word “data” comes from the Latin word datum, which means “something given.” The plural form of datum is data. This Latin origin is crucial to understanding why “data” has historically been treated as a plural noun.
Grammatical Classification
Traditionally, “data” is considered the plural form of “datum.” However, in modern English, “data” is increasingly used as an uncountable (mass) noun, especially in less formal contexts. This means it can be treated as singular, particularly when referring to a body of information as a whole.
Function in a Sentence
“Data” can function as the subject, object, or complement of a sentence. Its grammatical number (singular or plural) affects the verb form used with it and the pronouns that refer back to it.
Contexts of Use
The usage of “data” as singular or plural varies depending on the context. In scientific, academic, and technical writing, it is often treated as plural.
In more general or informal contexts, it is frequently treated as singular. For example, “The data are conclusive” (formal, plural) vs.
“The data is readily available” (informal, singular).
Structural Breakdown
Understanding the structural elements of “data” and its relationship to “datum” is essential for correct usage. This involves recognizing the singular and plural forms, as well as its function as an uncountable noun.
Singular Form: “Datum”
The singular form, “datum,” is rarely used in modern English, except in highly technical or mathematical contexts. It refers to a single piece of information.
For example, “Each datum represents a single observation.”
Plural Form: “Data”
Historically, “data” is the plural form of “datum,” and it should be used with a plural verb. This usage is still preferred in formal writing and scientific contexts.
For example, “The data were analyzed using statistical methods.”
“Data” as an Uncountable Noun
In contemporary English, “data” is often used as an uncountable noun, similar to “information” or “evidence.” In this case, it takes a singular verb. This usage is becoming increasingly common, especially in less formal settings.
For example, “The data is essential for our research.”
Types and Categories of Data
Data can be categorized in various ways depending on its nature and format. Recognizing these categories can help in understanding how “data” is used in different contexts.
Numerical Data
Numerical data consists of numbers and can be either discrete or continuous. Discrete data can only take specific values (e.g., number of students), while continuous data can take any value within a range (e.g., temperature).
Categorical Data
Categorical data represents characteristics or qualities and can be nominal (unordered categories, e.g., colors) or ordinal (ordered categories, e.g., rankings).
Textual Data
Textual data consists of words, sentences, and paragraphs. It can be analyzed using natural language processing techniques to extract meaning and insights.
Binary Data
Binary data is represented using 0s and 1s and is commonly used in computer science to store and process information.

Usage Rules for “Data”
To use “data” correctly, it’s important to understand the rules governing its usage, including considerations for formality, subject-verb agreement, and pronoun agreement.
Formal vs. Informal Usage
In formal writing and scientific contexts, it is generally recommended to treat “data” as plural. In informal contexts, treating “data” as singular is becoming increasingly acceptable.
Subject-Verb Agreement
When “data” is treated as plural, it should be used with a plural verb: “The data are conclusive.” When treated as singular, it should be used with a singular verb: “The data is essential.”
Pronoun Agreement
The pronoun used to refer back to “data” should agree in number. If “data” is treated as plural, use plural pronouns: “The data are available; they need to be analyzed.” If treated as singular, use singular pronouns: “The data is available; it needs to be analyzed.”
Exceptions and Special Cases
There are no strict exceptions, but the context and the intended audience should guide the choice of whether to treat “data” as singular or plural. Consistency is key; avoid switching between singular and plural usage within the same document or presentation.
Common Mistakes with “Data”
Several common mistakes arise when using “data.” Recognizing and avoiding these errors will improve the clarity and accuracy of your writing.
Incorrect Pluralization
A common mistake is to pluralize “data” as “datas,” which is incorrect. “Data” is already the plural form of “datum.”
Incorrect: The datas were analyzed.
Correct: The data were analyzed.
Incorrect Verb Agreement
Using a singular verb with “data” when it is intended to be plural (or vice versa) is another common error.
Incorrect: The data is conclusive (when intending plural).
Correct: The data are conclusive.
Incorrect: The data are essential (when intending singular).
Correct: The data is essential.
Misuse of “Datum”
Using “datum” when “data” is more appropriate, or in contexts where the singular form is not necessary, can sound overly formal or stilted.
Awkward: Each datum provides a unique perspective (when “data provides unique perspectives” would suffice).
