Get the official OCR AS Level Further Mathematics A Y532/01 Statistics mark scheme from the June 2025 exam series. This examiner-approved PDF contains detailed worked solutions, examiner commentary, assessment-objective breakdowns, method marks, accuracy marks and follow-through guidance for every question in the live OCR examination.

This OCR Y532/01 June 2025 mark scheme includes full examiner guidance for chi-squared goodness-of-fit testing, Poisson modelling, Spearman’s rank correlation coefficient, least-squares regression lines, variance optimisation and geometric distributions. The document explains how OCR awards M, A and B marks for rigorous statistical reasoning, probability modelling and algebraic interpretation, including detailed follow-through marking, acceptable alternative methods and contextual statistical conclusions. Questions include goodness-of-fit testing for biased dice, helicopter Poisson processes, regression reliability analysis, variance minimisation of discrete random variables and repeated Bernoulli-trial modelling. The mark scheme also provides detailed annotation guidance for OCR examiners, including handling of follow-through marks, significance testing conclusions and hypothesis-structure expectations. Pair it with the matching OCR Y532/01 June 2025 question paper on markscheme.net for complete examiner-standard revision and worked-solution practice. Updated for the 2025/2026 academic year, mobile-friendly and instantly downloadable from markscheme.net.

This document is designed for OCR AS Level Further Mathematics students preparing for the 2026 examination series, including independent learners, resit candidates and high-achieving mathematics students seeking examiner-level insight into Further Statistics marking standards.

Teachers, tutors, sixth-form mathematics departments and revision-course providers can use this examiner mark scheme for assessment-objective workshops, hypothesis-testing seminars, regression-analysis lessons, probability-modelling revision and worked-solution analysis. It is especially valuable for students aiming to improve rigorous statistical communication, analytical interpretation and high-band problem-solving skills in OCR AS Further Mathematics.
