| 설명 | 통계용어로 표본 평균치 분포의 표준편차를 나타내는 것이다. 표본 평균치가 모집단의 평균치 주위에 산재하는 것은 표본 크기와 모집단의 표준편차(σ)에 의해 지배된다. 표준오차(SD)는 이론적으로 σ/√N으로 나타낸다. |

standard error
| refractive errors | Deviations from the average or standard indices of refraction of the eye through its dioptric or refractive apparatus. (12 Dec 1998) |

| refractive | Serving or having power to refract, or turn from a direct course; pertaining to refraction; as, refractive surfaces; refractive powers. Refractive index. <medicine> The ratio of the sine of the angle of incidence to the sine of the angle of refraction for a ray passing out of one of the media into the other. Origin: Cf. F. Refractif. See Refract. Source: Websters Dictionary (01 Mar 1998) |

| refractive accommodative esotropia | That type of esotropia eliminated by correction of hypermetropic refractive error. (05 Mar 2000) |
| refractive amblyopia | A suppression of central vision due to an unequal refractive error (anisometropia) of at least two diopters. This induces a sufficient difference in image size (aniseikonia) that the two images cannot be fused. In order to avoid confusion, the blurrier image is suppressed. Synonym: refractive amblyopia. (05 Mar 2000) |
| refractive index | <microscopy> The ratio of the velocity of light in a vacuum to the velocity in some medium. Refractive index generally increases with the atomic number of the constituent atoms. (05 Aug 1998) |
| refractive keratoplasty | Any procedure in which the shape of the cornea is modified, with the intent of changing the refractive error of the eye; for example, if the cornea is flattened, the eye becomes less myopic. See: photorefractive keratectomy, keratophakia, lamellar keratoplasty, thermokeratoplasty, keratomileusis, radial keratotomy. Synonym: keratorefractive surgery. (05 Mar 2000) |
| refractive keratotomy | Modification of corneal curvature by means of corneal incisions to minimise hyperopia, myopia, or astigmatism.In this type of radial keratotomy surgery, performed by excimer laser, pie-shaped pieces of cornea are removed under local anaesthetic. The resulting scar tissue formation reshapes the cornea. This class of surgery is somewhat unpredictable, and its long-term effects are still unknown. (05 Mar 2000) |
| alpha error | The statistical error (said to be of the first kind or type I) made in testing an hypothesis when it is concluded that a result is positive when it really is not. Alpha error is often referred to as a false positive. (12 Dec 1998) |
| beta error | The statistical error (said to be of the second kind or type II) made in testing when it is concluded that something is negative when it really is positive. Beta error is often referred to as a false negative. (12 Dec 1998) |
| residual error | The estimated discrepancy between the actual measured datum and the value for that value computed after a model has been fitted to the set of the data by an estimator. (05 Mar 2000) |
| standard error of difference | A statistical index of the probability that a difference between two sample means is greater than zero. (05 Mar 2000) |
| standard error of the mean | A statistical index of the probability that a given sample mean is representative of the mean of the population from which the sample was drawn. (05 Mar 2000) |
| inborn error of metabolism | A genetic biochemical disorder of a specific enzyme that forms a metabolic block, e.g., phenylketonuria. (05 Mar 2000) |
| interobserver error | The differences in interpretation by two or more individuals making observations of the same phenomenon. (05 Mar 2000) |
| intraobserver error | The differences in interpretation by an individual making observations of the same phenomenon at different times. (05 Mar 2000) |
| technical error | That component of experimental error that is due to the conduct of the experiment and in principle estimated by replicate determinations on aliquots from the same specimen. (05 Mar 2000) |
