Study on Levels of Mathematically Gifted Students' Understanding of Statistical Samples through Comparison with Non-Gifted Students

摘要: The purpose of this study is to investigate levels mathematically gifted students` understanding statistical samples through comparison with non-gifted students. For purpose, rubric for was developed based on the responses tasks: no recognition a part population (level 0), consideration as subsets 1), quasi-proportional, small-scale version 2), importance unbiased 3), and effect random sampling 4). Based rubric, each student`s were identified. t tests conducted test statistically significant differences between students both elementary middle school graders, show that there difference Table frequencies level, however, shows not distributed at high but overlapped samples.
