Which term refers to the overall set of techniques used to summarize and describe data without making inferences about a population?

• A. Descriptive Statistics
• B. Inferential Statistics
• C. Frequency Distribution
• D. Histogram

Answer: (A)

Descriptive statistics describe and summarize the data you have, without trying to draw conclusions about a larger population. It covers numerical summaries like the mean and variability measures, as well as visual tools such as frequency distributions and histograms to show how the data are distributed. This is exactly what the question is asking for: an umbrella of techniques used to summarize and describe data rather than infer anything about a broader group. Inferential statistics, in contrast, is about making inferences or generalizations from a sample to a population, using methods like hypothesis tests and confidence intervals. Frequency distribution and histogram are specific descriptive tools that illustrate the data's distribution but don’t themselves define the entire approach.
