Histograms | OCR GCSE Higher Maths | 40 Worked Examples (J560)

A complete OCR GCSE (9-1) Higher Mathematics (J560) worked-solutions pack on Histograms, with 40 exam-style questions graded Easy to Challenging and every solution fully worked, line by line, with mark-scheme annotations in OCR’s own M/A/B code set. Built specifically for OCR: the pack opens with a ‘what you must know by heart’ box because J560 gives students no formula sheet, so the frequency density relationship has to be recalled cold. Coverage spans the whole topic (spec 12.02b): converting frequency tables to frequency densities, drawing and completing histograms with unequal class widths, reading frequencies as areas, estimating numbers within part of a class, estimating the mean, median, quartiles and interquartile range by interpolation, comparing two distributions, and the AO3 ‘choose a threshold for the top 25%’ style problem straight out of OCR papers. Clear TikZ histograms sit inline with the questions and the constructed answers appear in the solutions. Ideal for revision, homework, cover lessons and one-to-one tuition. Answers included.
