SALTS
A graph visually represents data, which can be categorized into quantitative (numerical) and qualitative (descriptive). Geographers use graphs to answer questions, solve problems, and make decisions, requiring data to be accurate, relevant, and appropriately presented.
SALTS for Graph Construction:
Scale: Label measurement units.
Axis: Clearly label each axis.
Legend: Explain graph colors, shading, lines, or symbols.
Title: Describe the data and year of collection.
Source: Indicate data origin.
Types of Graphs Include:
Column Graph
Line Graph
Cumulative Line Graph
Pie Charts
Climate Graphs
Population Profiles
Scatter Graphs
Reading Graphs:
To interpret a pie chart, consider the title, identify which country produces the most rubber, and quantify production percentages and quantities (e.g., data from 2018).
Interpreting Graphs:
Use the PQE method: identify patterns in data distribution, quantify with evidence, and look for anomalies (outliers).
