Table 2.
Statistical parameters obtained in the paired Student’s t-test for the comparison of examiners F and C regarding the measurement of mean left masseter area (mm2) and mean left masseter volume (mm3) of ten patients by MRI
| Examiner comparison | Mean difference* | Standard deviation of differences | Degrees of freedom (df) | Test statistic from paired t-test | P-value from paired t-test |
|---|---|---|---|---|---|
| Examiner F versus examiner C, left masseter muscle area (mm2) | −4.633 | 79.466 | 29 | −0.319 | 0.752 |
| Examiner F versus examiner C, left masseter muscle volume (mm3) | −14.833 | 94.659 | 29 | −0.858 | 0.398 |
*The mean difference is significant at the 0.05 level
