Responses of 223 students in grades 6 to 11 to questions related to beliefs about getting out of bed on the left side are analysed from two perspectives. On one hand the items explore subjective beliefs about chance. On the other hand the different wording and context of the items provide opportunity to show different levels of understanding of students' explanations. Rasch analysis is used to place the items on a scale with other statistical literacy items in order to suggest potential levels of difficulty.
