Types of Statistical Data Representation
Which of the following is not a diagrammatic representation of data-
- Pictogram
- Cartogram
- 1-D, 2-D & 3-D diagram
- Histogram — Correct Answer
Explanation:
Correct Answer (NOT a diagrammatic representation): Histogram
In statistics, data is represented either by Diagrams or Graphs — these are two distinct categories. A Histogram is a graphical representation, not a diagrammatic one.
Diagrams vs Graphs — Classification
| Type | Examples | Key Feature |
|---|---|---|
| Diagrams | Pictogram, Cartogram, 1-D diagrams (bar), 2-D diagrams (pie chart), 3-D diagrams | Visual/pictorial; may not use mathematical axes |
| Graphs | Histogram, Frequency polygon, Frequency curve, Ogives, Historigram, Line graph | Plotted on mathematical coordinate (X-Y) axes |
Quick Definitions
- Pictogram: Uses pictures/symbols to represent quantities
- Cartogram: Diagrammatic representation on a geographical map
- 1-D, 2-D, 3-D diagrams: Bar charts (1-D), pie charts (2-D), 3-dimensional representations
- Histogram: Graphical (not diagrammatic) — rectangles showing frequency distribution of continuous data on X-Y axes
