Every graph in the IB Geography toolkit, three ways: name it, choose it, describe it. Run this before a summative, run it again in exam week.
A graph appears with no caption. Name the technique, then say what it is actually good for. Both halves earn marks in Paper 1.
You are handed a dataset. Pick the technique that displays it properly. The wrong answers are the ones students actually reach for.
A live resource, generated fresh each time. Describe what it shows. You are marked on trend, rate of change, anomaly and quantified evidence, and penalised the moment you start explaining why.
Module 2, Lesson 12. Plot a development indicator against wealth, read the scatter, calculate Spearman's rank, test it for significance, then describe the relationship without explaining it.
Rank both variables, find the difference in rank for each country, square it, then substitute into the formula. The table below does it for the indicator you selected.
Correlation lab figures are indicative and rounded, drawn from World Bank and UN style indicators for the most recent full year. Use them for technique practice, not as citable data in an IA.
