In data analytics, what term refers to all possible data values in a dataset?

• A. Sample
• B. Universe
• C. Population
• D. Range

Answer: (C)

All possible data values in a dataset are called the population. This represents the complete set of units or observations under study, such as every student in a school or every transaction in a day. When you collect data from only part of that group, you have a sample, which you use to infer characteristics of the population without measuring everything. The range, on the other hand, is just the spread between the smallest and largest values, not the whole set of values. Universe is sometimes used informally to mean the same idea, but the standard term in statistics and data analytics is population.
