What is a PEA analysis and how do I do one? Sometimes, a PEA analysis can be called TEA analysis, when the word Trend is used instead of pattern.
To obtain full marks in one of these questions, make sure that you answer/refer to the main ideas in Patterns, Evidence and Anomalies.
Patterns
This could include Maps and bar graphs or line graphs. Here’s what to look at.
Maps/ bar graphs
- Highest and lowest occurrence
- Areas of high and low concentration
- Overall trends
Line Graphs
- Major movements
- Used adverbs – rises/falls: slowly, gradually, rapidly, exponentially, sharply
- Oscillations – reoccurring shifts from high to low
- Correlations – positive or negative/ direct or inverse
- Prompt will contain the world relationship
Evidence
where or how much?
- Quantification – Scale or Key data
- World regions – Eastern Europe, S.E. Asia, Central America
- Countries – Eastern Cambodia, Russia
- Oceans/ Seas – Andaman sea, Southern Pacific
- Lines of latitude/ longitude
Anomalies
Something that doesn’t fit the pattern or identify areas of high variability
To get full marks in this question, you must refer to an anomaly.
