Which of the following refers to the notion that the data file actually contains the information that the researcher is trying to obtain to adequately address research questions?

A method of handling missing data in which only the actual variables for a respondent that do not contain information are eliminated from use in statistical analyses is called ____________________.

Precoding is the tallying of a small sample of the total number of replies to a particular question,

A questionnaire with 5% or more of the responses is suspect and should be deleted from further analyses.

When Arbitron has its own staff verify the accuracy of radio-station call letters (e.g.KMOX)to ensure that they are possible radio call letters in the geographical area of the respondent,this is an example of:

A collection of related fields that represents the responses from one sampling unit is known as a:

A collection of related records that make up a data set is called a(n)____________________.
