Table X below contains data on the distribution of Groundnut production in four regions of country M in the year 2013. Use the data in the table to answer the questions that follow.
| Country | Groundnut production in metric tones |
| A | 100,000 |
| B | 260,000 |
| C | 200,000 |
| D | 80,000 |
(a) Using the map of country M and a scale of one dot to represent 20,000 metric tonnes, produce dots to represent the data.
(b) State three disadvantages of dot maps.
Map of country M showing groundnut production in the year 2013
Production of dot map, calculation of dots
A = \(\frac{100,000}{20,000}\) = 5 dots
B = \(\frac{260,000}{20,000}\) = 13 dots
C = \(\frac{200,000}{20,000}\) = 1 dots
D = \(\frac{80,000}{20,000}\) = 4 dots
(b) Disadvantages of dot map:
- Difficult to find dot value to show high and low densities.
- Difficult to represent fractional dots.
- Difficult to calculate actual values of production from dot maps
- Dots may coalesce
- Evenly spread dots over the various areas may not reflect true distribution.
- Avoiding boundary lines in the placement of dots create false impression about their production
- Areas without dots give false impression about the distribution,
-Dots may be placed in areas representing other features, e.g marshes, lakes, rivers, mountains.
