Secondary school students’ understanding of Verbal Probability Expressions
Secondary school students’ understanding of Verbal Probability Expressions
The probability or likelihood of an event occurring can be communicated numerically or by using a verbal probability expression (VPE) such as possibly, certain, or likely. VPEs are ‘adjectives (often qualified by adverbs) that express risk or uncertainty’ (Collins & Hahn, 2018, p. 68). In this study we examine data collected from approximately 200 secondary school students via an online survey. Students were asked to use a slider to indicate a numerical equivalent for 29 expressions taken from Willems et al. (2020) combining a VPE and a context, for example, ‘it is generally the case that everything fits in the suitcase’. We will share our findings indicating the levels of agreement and variability in students’ interpretations of these expressions, as well as their relationship to age. We discuss some of the implications for the teaching and learning of probability, as well as wider implications.

Abstract
The probability or likelihood of an event occurring can be communicated numerically or by using a verbal probability expression (VPE) such as possibly, certain, or likely. VPEs are ‘adjectives (often qualified by adverbs) that express risk or uncertainty’ (Collins & Hahn, 2018, p. 68). In this study we examine data collected from approximately 200 secondary school students via an online survey. Students were asked to use a slider to indicate a numerical equivalent for 29 expressions taken from Willems et al. (2020) combining a VPE and a context, for example, ‘it is generally the case that everything fits in the suitcase’. We will share our findings indicating the levels of agreement and variability in students’ interpretations of these expressions, as well as their relationship to age. We discuss some of the implications for the teaching and learning of probability, as well as wider implications.
