A data set (or dataset) is a collection of data, usually presented in tabular form. Each column represents a particular variable. Each row corresponds to a given member of the data set in question. It lists values for each of the variables, such as height and weight of an object. Each value is known as a datum. The data set may comprise data for one or more members, corresponding to the number of rows.
Nontabular data sets can take the form of marked up strings of characters, such as an XML file.

Famous quotes containing the words data and/or set:
“Mental health data from the 1950’s on middle-aged women showed them to be a particularly distressed group, vulnerable to depression and feelings of uselessness. This isn’t surprising. If society tells you that your main role is to be attractive to men and you are getting crow’s feet, and to be a mother to children and yours are leaving home, no wonder you are distressed.”
—Grace Baruch (20th century)
“If nations always moved from one set of furnished rooms to another—and always into a better set—things might be easier, but the trouble is that there is no one to prepare the new rooms. The future is worse than the ocean—there is nothing there. It will be what men and circumstances make it.”
—Alexander Herzen (1812–1870)
