Answer to Question 1

Researchers organize coded data into fields, records, and files. A field is a collection of characters (a character is a single number, letter, or special symbol such as a question mark) that represents a single piece of data, usually a variable. Text variables are represented by string characters, which is computer terminology for a series of alphabetic characters (non-numeric characters) that may form a word. A record is a collection of related fields. Researchers may use this term to refer to one respondent's data. A data file is a collection of related records that make up a data set. Finally, value labels allow a word or short phrase to be associated with a numeric value.
