The Influence of Variation and Expectation on the Developing Awareness of Distribution
Watson, Jane M.
Statistics Education Research Journal, v8 n1 p32-61 May 2009
This study considers the evolving influence of variation and expectation on the development of school students' appreciation of distribution as displayed in their construction of graphical representations of data sets. Three interview protocols are employed, presenting different contexts within which 109 students, ranging in age from 6 to 15 years, could display and interpret their understanding. Responses are analyzed within a hierarchical cognitive framework. It is hypothesized from the analysis that, contrary to the order in which expectation and variation are introduced in the school curriculum, the natural tendency for students is to acknowledge variation first and then expectation. (Contains 8 tables and 21 figures.)
