There are a number of definitions of the term "dataset." Many books and articles use the term without defining it, as if it is self-explanatory. Data-Planet defines "dataset" as "A collection of related data items, eg, the responses of survey participants." (Data-Planet 2015). The Cambridge Dictionary of Statistics (4th Edition - 2006) defines a "data set" as a "general term for observations and measurements collected during any type of scientific investigation."
