Which statement best describes descriptive statistics?

Which statement best describes descriptive statistics?

• A. Summarize or display data for quick overview
• B. Test hypotheses about a population
• C. Estimate population parameters
• D. Infer causal relationships

Answer: (A)

Descriptive statistics focus on describing the data you have. They summarize and display data to give a quick, clear overview of what the dataset looks like. This includes measures of center (like the mean, median, and mode), measures of spread (such as range, variance, and standard deviation), and visuals (histograms, bar charts, boxplots) that show the distribution and patterns in the data. They do not attempt to infer or make claims about a larger population, estimate population parameters, or establish causal relationships. So describing data with a simple summary of its behavior and a few graphs best matches descriptive statistics.
