Difference in framing bias between low and high performance groups for each numeracy measure | ||||
Group (n)^{a} | Schwartz-J | Lipkus-J^{9} | ||
Low (119) | High (181) | Low (139) | High (161) | |
Numeracy score (Median ± IQR) | 2 ± 1 | 3 | 7 ± 2 | 9 |
Difference in rated risk (mean ± SD)^{b} | −0.22 ± 0.85 | −0.02 ± 0.81 | −0.22 ± 0.89 | −0.00 ± 0.78 |
^{a}n, number of respondents in each group.
^{b}Difference in rated risk was calculated as the difference between survival-rate frame scores and death-rate frame scores. Scores between subgroups were compared using non-parametric methods, but means are presented because median scores did not show differences between sub-groups.
