A 2 × 2 Contingency Table for Optimal Lowercase Benchmark
| Lowercase letter-naming benchmark (15) | Letter-Word Identification
|
|
|---|---|---|
| At risk | Not at risk | |
| Does not meet (fail) | 37 | 123 |
| Meets (pass) | 16 | 195 |
Note. Using Table A3, sensitivity for the lowercase letter benchmark is calculated with 37/(37 + 16) = .70; specificity is 195/(123 + 195) = .61; positive predictive power is 37/(37 + 123) = .23; and negative predictive power is 195/(16 + 195) = .92.
