Resources Title Organisation Description Ref OCR Students could investigate the variation in values calculated from different p21, p22, samples from the pre-release LDS to be used in the AS/A Level 2018 and p23, p24 A Level 2019 and p25 OCR Students could investigate the variation in values calculated from different p21, p22, samples from the pre-release LDS to be used in the AS Level 2019 and A p23, p24 Level 2020 and p25 OCR Students could investigate the variation in values calculated from different p21, p22, samples from the pre-release LDS to be used in the AS Level 2021 and A p23, p24 Level 2021 and p25 MEI A commentary of the underlying mathematics, a sample resource, a use of p21, p22, technology, links with other topics, common errors, opportunities for proof p23, p24 and questions to promote mathematical thinking. and p25 OCR Learners will investigate how increasing the size of a sample impacts the p21, p22, sampling error. Initially they will use the LDS to randomly select a small p23, p24 number of local authorities. They will calculate the percentage of workers and p25 who travel by bike. Learners will compare their percentage with peers with a similar size sample. Learners will then take samples of increasing size, comparing the sample mean with the population mean. This activity covers all aspects of Statistical Sampling.
