Final answer:

In a data dictionary, the term that specifies whether the data element contains numeric, alphabetic, or character values is the 'type'. It is crucial for correctly representing and managing data in a database system.

Step-by-step explanation:

In a data dictionary, the term that refers to whether the data element contains numeric, alphabetic, or character values is known as the type. This concept is fundamental to understanding how data is structured in databases and information systems. Each data element within a data dictionary has an associated type that defines the kind of data it represents. For example:

  • The number of pairs of shoes you own would be a quantitative discrete data type because it represents a countable number of items.
  • The type of car you drive would fall under qualitative data type because it describes a category or quality rather than a numeric value.
  • The distance from your home to the nearest grocery store would likely be considered quantitative continuous data because it can take an infinite number of values within a range.

Within a data dictionary, properly identifying the data type helps ensure that the element is used correctly in the database and that the right kind of data is stored. For instance, knowing whether data should be treated as a string or an integer is crucial when performing sorting, querying, or applying constraints on the data.
