Mixed Data: key points

Data interpretation questions give a table or chart and ask you to calculate totals, averages, ratios and percentage changes from it.

  • Read the title and the units of the table before the questions.
  • Percentage change = (new − old) / old × 100.
  • Average = total / number of entries.
  • Approximate where the options are far apart; calculate exactly where they are close.
