Definition
Data having two or more variables per object.

Note
The measurements results are often of the same kind of quantity.

Examples
1) Absorbances measured at \(\pu{101}\) wavelengths in the range \(\pu{200 nm}\) to \(\pu{400 nm}\).
2) Mass fractions of \(\pu{10}\) elements measured by ICP-MS.
