Grouped and ungrouped data both appear: finding a mean from raw exam marks, estimating from grouped speed data for cars passing a school gate, and completing frequency-table calculations for pumpkin masses or temperature ranges all test handling data correctly.
Find, complete, work out, estimate and show are the top command words, worth from 1 to 11 marks, across 21 questions set in 2025 papers. Because estimate signals that grouped data only allows an approximate answer using midpoints, practise distinguishing when a mean can be calculated exactly against when it must be estimated, then use instant marking to check whether your method matched what the command word actually required.
