Why is data and information are used interchangeably?

The term data means groups of information that represent the qualitative or quantitative attributes of a variable or set of variables. Data (plural of datum, which is seldom used) are typically the results of measurements and can be the basis of graphs, images, or observations of a set of variables. Data are often viewed as the lowest level of abstraction from which information and knowledge are derived.

So no they cannot be used interchangeably.
