Study Notes
Population Distribution and Graphs
- Sparsely populated areas are discussed.
- Factors influencing global population distribution are examined.
- Population concepts like optimum, underpopulation, and overpopulation are defined.
- Population problems in developed and developing countries are explored, including solutions.
- Population growth factors (birth rate, death rate, rapid growth) and effects are analyzed.
- Methods for controlling population growth are identified.
Population Structure
- Population pyramids illustrate population structure.
- Sex and age composition are crucial components of population structure.
Graph Construction: Group or Comparative Line/Curve Graphs
- Multiple lines are used to depict various variables on the same graph.
- Lines should be distinct (e.g., different colors).
- A maximum of five lines is recommended, though more can be used if necessary.
- Lines should not cross unless the data warrants it; use varying colors/shading when crossing.
- Lines should not touch the vertical axis.
- Variable names are directly labeled on each line.
Graph Construction: Divergence Bar Graphs
- Divergence bar graphs utilize a zero line (average value).
- Values above/below the average line are plotted accordingly.
- Scale selection depends on calculated divergences.
- Negative values are plotted below the zero line.
- Positive values are plotted above the zero line.
Graph Construction: Simple Bar Graphs
- A simple bar graph represents a single dependent variable.
- Bar height corresponds to the dependent variable's volume/percentage.
- Bars should be separated from the vertical axis and have uniform sizes.
- Attached bars represent a single variable (e.g., rainfall).
- Separated bars represent different variables (e.g., different companies).
Graph Construction: Simple Divided Circles (Pie Charts)
- A circle represents the total data.
- The circle is divided proportionally to the values of the variables, starting with the largest segment.
- Segments are labeled, and distinct colors/shading are used.
- Largest segments should be positioned at the 12 o'clock position.
