What describes ungrouped data?

• A. Discrete data, where the frequency is shown in terms of a specific measure / value
• B. Data organized into class intervals
• C. Data summarized in a histogram
• D. Data that has been aggregated into groups

Answer: (A)

Ungrouped data means the raw observations are not placed into ranges or classes; you keep each value as observed and typically show how often each exact value occurs. This fits discrete data, where frequencies are tied to specific values. When data are grouped, you arrange values into class intervals (like 0–9, 10–19) and summarize frequencies by those ranges, which is why options describing class intervals, histograms of intervals, or aggregated groups point to grouped data instead.
