Interpretation
Akopọ
Three statements, all Core, and between them they carry the part of statistics that cannot be done by a calculator. Anybody can find a mean. The marks in this topic go to the candidate who can say what a graph is telling them, compare two sets of data in a sentence that a reader could act on, and know exactly how far a line of best fit can be trusted before it becomes a guess.
You will read and interpret a wide range of graphs and diagrams and draw conclusions from them; compare distributions and make inferences; and recognise correlation and draw or use lines of best fit by eye while understanding what these represent. The specification's own note names the vocabulary you must use for the last of those: positive correlation, negative correlation, no correlation, weak correlation and strong correlation.
