Drawing the time-series diagram (description for construction):
- On the X-axis (horizontal) mark the five time periods in order: 1990-92, 2000-02, 2005-07, 2010-12, 2014-16, at equal distances.
- On the Y-axis (vertical) take a suitable scale for the percentage of malnourished people, say 1 cm = 5%, ranging from 0 to 25.
- Plot the points against each period — 24, 18, 21, 16 and 15 — and join them with straight line segments to obtain the time-series (line) curve. Give the diagram a title ('Percentage of malnourished people in India') and label both axes.
Analysis of the data:
| Period | Malnourished (%) | Change |
|---|---|---|
| 1990-92 | 24 | — |
| 2000-02 | 18 | fell by 6 |
| 2005-07 | 21 | rose by 3 |
| 2010-12 | 16 | fell by 5 |
| 2014-16 | 15 | fell by 1 |
- Malnutrition declined sharply from 24% (1990-92) to 18% (2000-02).
- It then rose to 21% (2005-07) — a temporary setback / interruption in the improvement.
- Thereafter it fell again to 16% (2010-12) and 15% (2014-16). …
