A. Short Notes
1. Scale.
Ans: A scale is a system of levels or numbers used for measurement or comparison. For example, an earthquake’s magnitude may be rated 5.5 on the Richter scale, while a patient might evaluate therapies on a scale from zero to ten to indicate their effectiveness or satisfaction.
2. Types of Scale.
Ans: Psychologist Stanley Stevens developed four common scales of measurement: nominal, ordinal, interval, and ratio. Each scale has distinct properties that guide data analysis. These properties include identity (distinguishing categories), magnitude (ordering), equal intervals (consistent differences), and a true zero point (absence of the measured attribute).
3. Graphical Scale.
Ans: A graphical scale is a visual tool used to represent data or measurements on a graph or chart. It often includes bar charts, line graphs, or histograms to display the distribution, trends, or comparisons of data. By using visual elements, a graphical scale helps in easily interpreting and understanding quantitative information.
5. Statement Scale.
Ans: A statement scale is a type of map scale that uses a written statement to describe the relationship between map distance and ground distance. For example, a statement scale might read, “1 centimeter represents 1 kilometer.” This can also be expressed in short as 1cm represent 10km or 1cm to 10km.
Short Type Question And Answer
1. What is the purpose of a scale on a map?
Ans: To show the relationship between map distance and ground distance.
2. What are the three types of scale?
Ans: Statement, Representative Fraction, and Graphical Scale.
3. What is a Representative Fraction?
Ans: A ratio of map distance to ground distance, expressed as 1:n.
4. What is a Graphical Scale?
Ans: A line representing the ratio of map distance to ground distance.
5. How is a Statement Scale expressed?
Ans: As a written statement, e.g. 1 cm = 10 km.
6. What is the difference between a Representative Fraction and a Graphical Scale?
Ans: The difference between a Representative Fraction and a Graphical Scale :
| Basic of Difference | Representative Fraction | Graphical Scale |
| Meaning | Representative Fraction (RF) is a scale method expressed as a ratio or fraction, showing the relationship between a unit distance on a map and the corresponding distance on the ground. For example, an RF of 1:50,000 means 1 unit on the map equals 50,000 units on the ground. | The graphical scale represents the same ratio as a numerical scale but is shown as a ruler or bar on the map, graduated from 0 to values corresponding to actual distances. Unlike the numerical scale, the graphical scale cannot be read directly; instead, distances are estimated by comparing measurements on the map to the scale. |
| Usage | It provides a precise and universal measure that is independent of the map’s size or format. It can be used to calculate real-world distances and areas by multiplying the map distance by the RF ratio. | Useful for quick, visual reference and is often included on maps for easy distance estimation. It can be less precise than RF for detailed calculations but is more intuitive for visual inspection. |
7. Explain the importance of scale in map making and how it is used to represent geographical data.
Ans: Scale is essential in map making as it allows us to represent large areas on a small sheet of paper. It helps us to understand the relationship between map distance and ground distance, enabling us to measure distances and areas on the map. Scale is used to represent geographical data such as population, land use, and economic activities.
