Correct Matching
| Term | Match | Full Definition |
|---|---|---|
| Cartogram (1-e) | Diagrammatical representation of data with geographical location | Data is plotted on a map, showing geographic distribution (e.g., rainfall maps, livestock density maps) |
| Pictogram (2-d) | Pictorial representation of data | Uses pictures or symbols (e.g., cow icons) to represent quantities; most visually intuitive |
| Historigram (3-a) | Graph of time series | Data values plotted against time on X-axis; also called Line graph; NOT a frequency distribution graph |
| Histogram (4-b) | Graphical representation of frequency distribution of a continuous variable | Adjacent rectangles with no gaps; X-axis = class intervals; Y-axis = frequency; area = frequency |
| Frequency curve (5-c) | Joining the points of frequency polygon by free-hand smoothed curve | Smooth bell-shaped curve drawn through frequency polygon points; represents theoretical distribution |
Diagrams vs Graphs — Quick Reference
- Diagrams: Pictogram, Cartogram, Bar (1-D), Pie (2-D), 3-D — visual/pictorial, no strict axes required
- Graphs: Histogram, Frequency polygon, Frequency curve, Ogives, Historigram — plotted on mathematical X-Y coordinate axes
