Descriptive statistics are defined as which of the following?

• A. Procedures that organize data.
• B. Statistical procedures used to summarize, organize, and simplify data.
• C. Techniques to infer population parameters.
• D. Methods to estimate sampling error.

Answer: (B)

Descriptive statistics are the tools that summarize and organize data so we can see patterns at a glance. They aim to simplify the data into concise summaries, such as measures of central tendency (mean, median, mode) and variability (range, standard deviation), and ways of presenting the data. The description that best fits this idea is that descriptive statistics are procedures used to summarize, organize, and simplify data. They focus on describing the data we have, not on making inferences about a larger population. In contrast, inferring population parameters or estimating sampling error involves inferential statistics, which go beyond mere description. So, the chosen statement captures the core purpose: to summarize, organize, and simplify data.
