Which component is typically included under descriptive statistics?

• A. Measures of Central Tendency
• B. Correlation Coefficient
• C. Inferential Statistics
• D. Statistical Significance

Answer: (A)

Descriptive statistics aim to summarize a dataset with numbers that describe its center and spread, giving a clear picture of the data at hand. The most direct way to express the center of the data is through measures of central tendency—mean, median, and mode. These values tell you the typical or middle value around which the data cluster, which is exactly what descriptive statistics strive to convey about the sample. The other ideas point to different goals: the correlation coefficient describes how two variables move together, which is about relationships rather than a single dataset's center; inferential statistics involves drawing conclusions about a larger population from the sample, and statistical significance is a judgment about whether observed patterns are likely due to chance, a hallmark of inferential reasoning. So measures of central tendency are the hallmark component typically included under descriptive statistics.
