Two pupils of the same age sit the same IQ test, which is written in English. The table shows their IQ scores, their experience of English and how they did on a practical design task set by their school.
| Pupil | IQ score | Experience of English | Practical design task |
|---|---|---|---|
| Aisha | 86 | Has been learning English for one year | Produced an original design that worked |
| Josh | 115 | Has spoken English since early childhood | Produced a less original design that worked |
Josh's IQ score is 29 points higher than Aisha's. Using the table, explain two reasons why comparing their IQ scores may give a misleading picture of their intelligence.
30 exam-style questions on OCR GCSE Psychology 2.1 Key Concepts, covering 2.1.1 Stages of development, 2.1.2 Brain development and the nervous system, and 2.1.3 IQ tests as a measure of intelligence. Each one has a worked solution and a mark scheme showing where the marks go.
