Two practice IA1 data tests for QCE Psychology Unit 3 (2025 syllabus), with editable Word papers and marking guides. Each test: three unseen datasets, 20 marks, 60 minutes plus 5 minutes perusal, with a 6/6/8 split across Objectives 2, 3 and 4 and verbs from the syllabus question specifications. Test A: duration of short-term memory (after Peterson & Peterson, 1959); extinction after different reinforcement schedules (Skinner box); perceptual set (after Bugelski & Alampay, 1961). Test B: levodopa and finger tapping in Parkinson’s disease (placebo-controlled); levels of processing (after Craik & Tulving, 1975); extinction and spontaneous recovery (after Pavlov). Marking guides include expected responses, mark-by-mark criteria, graph-reading tolerances, error-carried-forward rules, common student errors and a raw-mark to IA1 (/10) conversion table using the ISMG cut-offs. Suitable for formative practice before IA1 and for external assessment revision. Datasets are fictional. Independent resource, not produced or endorsed by the QCAA.

One-page pre-submission checklist for QCE Psychology IA1 data tests (2025 syllabus), based on the QCAA’s published endorsement findings.

Checks cover: Alignment: question focus vs objective, the 2025 question specifications, datasets from the listed Unit 3 practicals and case studies, no methodology questions. Scope and scale: objective mark split, variety of data and item types, calculation complexity, central tendency suited to the data. Transparency: cueing multi-mark questions, labelled error bars, formulas provided. Marking scheme: expected responses tied to the verb, a characteristic for every mark. Editable Word and PDF.
