Which option is NOT a common descriptive statistic?

• A. Measures of Central Tendency
• B. Measures of Dispersion
• C. Inferential Statistics
• D. Measures of Frequency Distribution

Answer: (C)

Descriptive statistics summarize the data you have. They describe central location, variability, and how data are distributed. Central tendency measures (like the mean, median, and mode) tell you where data cluster. Measures of dispersion (such as range, variance, and standard deviation) show how spread out the data are. Measures of frequency distribution describe how often values occur across different intervals or categories. Inferential statistics, in contrast, use sample data to make inferences about a larger population, including estimates, hypothesis tests, and confidence intervals. Since it goes beyond describing the observed data to draw general conclusions, it is not a descriptive statistic. The other categories are all descriptive tools used to summarize and describe the data directly.
