Mathematics Education Research Group of Australasia, Paper presented at the Annual Meeting of the Mathematics Education Research Group of Australasia (33rd, Freemantle, Western Australia, Jul 3-7, 2010)
Two test items that examined high school students' beliefs of sample size for large populations using the context of opinion polls conducted prior to national and state elections were developed. A trial of the two items with 21 male and 33 female Year 9 students examined their naive understanding of sample size: over half of students chose a sample size of "10% of the population", and a quarter chose a sample size of 15,000--both approaches grossly exceeding the accepted sample size. (Contains 6 tables.) [For the complete proceedings, "Shaping the Future of Mathematics Education.
