A numerical value describing a sample is called a

• A. Parameter
• B. Statistic
• C. Descriptive Statistics
• D. Inferential Statistics

Answer: (B)

A numerical value describing a sample is a statistic. It is a summary that comes from the sample data itself, not from the entire population. The quantity that would describe the whole population is a parameter. Descriptive statistics refers to the overall practice of summarizing sample data with measures like the sample mean or standard deviation, which are statistics themselves. Inferential statistics uses those sample results to make inferences about population parameters. So the single numeric value you compute from the sample fits the term statistic.
