verbal expressions of probability  

Definición

  • Verbal expressions of probability are those used for communicating degrees of uncertainty, such as likely, very likely, possible, and uncertain, in contrast with numerical expressions, such as “The probability of X is 70%” or “The odds are 3 to 1.” Correspondence between Verbal and Numerical Expressions Since the 1960s, several authors have studied the equivalence between verbal and numerical expressions of probability. The typical experiment consists in selecting a set of linguistic expressions, asking a group of subjects to translate each one into a percentage or a number between 0 and 1, and building a table or a graph that summarizes the results.
