What are numerical values based on data from the sample?

• A. Variables
• B. Constants
• C. Stats
• D. Statistics

Answer: (D)

When you summarize data from a sample with numerical values, those numbers are statistics. A statistic is a numerical summary computed from the sample data—think of the sample mean, sample standard deviation, or sample proportion. This contrasts with a population parameter, which would describe the entire group you’re trying to learn about. A variable is the characteristic being measured that can vary across observations, and a constant is a fixed value that doesn’t depend on the data. Since the question refers to numerical values derived from the sample data, the appropriate term is statistics.
