Describing Middle School Students' Organization of Statistical Data.
Johnson, Yolanda; Hofbauer, Pamela
The purpose of this study was to describe how middle school students physically arrange and organize statistical data. A case-study analysis was used to define and characterize the styles in which students handle, organize, and group statistical data. A series of four statistical tasks (Mooney, Langrall, Hofbauer, & Johnson, 2001) were given to twelve students, 4 from each of grades 6-8, in an interview format. Based on an analysis of the interview data, five categories for students' arrangement strategies emerged: No Arrangement (students made no attempt to arrange the data); Clustered Arrangement (students sorted the given data in groups with no totals); Sequential Arrangement (students listed data in least to greatest order or alphabetical order); Summative Arrangement (students provided totals for categories or groups of data); and Regrouped-Summative Arrangement (students re-grouped the data into new categories and gave totals). This study implies that students need to be presented with raw, unorganized data sets in addition to organized data sets and ask students to arrange or rearrange data in a meaningful way. (Author)
