One row is one country's exports of one commodity in one year: Country, Commodity, Year, Export_tons. Four countries, four commodities, 2015 to 2022.
This is the teaching copy of 103 rows: the 100 rows as supplied plus 3 exact duplicates, with 7 variant country spellings, 3 impossible tonnages and 2 blank years added on purpose. 38 of the original rows already shared a key with another row. The book Can I Trust This Data? finds and fixes every one.
