ellauri100.html on line 539: The other scale is the Subjective Numeracy Scale by Angela Fagerlin and colleagues, which measures individuals’ preference for numerical information. Numeracy (adapted from the term ‘literacy’) represents individuals’ ability to comprehend and use probabilities, ratios, and fractions. Traditional measures of numeracy ask people to perform mathematical operations, such as ‘If person A’s risk of getting a disease is 1% in 10 years, and person B’s risk is double that of A’s, what is B’s risk?’ However, some participants find these types of problems stressful and unpleasant, plus they are difficult to score in online studies. Subjective numeracy measures (like the scale you just took) are shown to be equally good measures of numeracy, without burdening participants.
