The unadjusted raw performance means and standard deviations for SATs scores for English, spelling, handwriting, creative writing, reading, mathematics, and science across the noise contours (dBALeq)
| Noise contour band | |||||||
|---|---|---|---|---|---|---|---|
| Performance indicator Mean SD | <54 | 54>57 | 57>60 | 60>63 | 63>66 | 66>69 | 69>72 |
| The test for a noise effect for performance unadjusted for any factor noise coefficents and standard errors are as follows: English −0.7 (0.34); spelling −0.04 (0.05); handwriting −0.02 (0.02); creative writing −0.13 (0.10); reading −0.52 (0.21); mathematics −0.81 (0.32); science −0.46 (0.31). The effect is statistically significant for English, reading and mathematics and not for any of the other performance outcomes. | |||||||
