PEA Analysis


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.


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


 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



Something that doesn’t fit the pattern or identify areas of high variability
