Value of all observations of a variable for the elements of a sample.

• A. Data set
• B. Observations
• C. Data capture
• D. Univariate data

Answer: (A)

When you measure one variable for every element in a sample, all those measured values together form a data set. It’s the complete collection you analyze, while each individual value is an observation. The data are univariate because only one variable is involved, but the term that names the whole collection is data set. Data capture isn’t the standard term for this idea, and observations refer to the individual measurements rather than the entire collection.
