Students' informal inference when exploring a statistical investigation
Résumé
This paper reports on preliminary results of a study aiming to identify informal inference aspects that emerge when grade 8 students explore a statistical investigation using the software TinkerPlots for data handling. Examples from students' work on one task in a sequence, designed to engage students in posing statistical questions about meaningful phenomena, in collecting and representing data and finally in making data-based inferences , illustrate how informal statistical inferences emerge. The results provide suggestions for further research and some educational implications are drawn.
