DATA. : SINGULAR OR PLURAL??

"Surprise! The word ""data"" can be singular or plural, depending on how people use it. Let’s break it down:

When Data is plural
""Data"" is the plural of ""datum,"" which means a single piece of information. So, in technical fields like engineering, the word ""data"" is typically treated as plural, especially in formal writing or reports.
Example: ""The data were collected from multiple sensors.""

When Data is singular
But in software engineering or data science, ""data"" is often treated as a singular mass noun, similar to ""information."" Because people think of ""data"" as a collection rather than individual points.
Example:""The data is stored in the cloud.""

In everyday English, most people now treat ""data"" as a singular word
Example: "" The data is interesting.""

So in casual conversation, it's okay to use data as singular. Both ways are correct, in different contexts!
