| 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
| 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) |

| chi-square | A statistical technique whereby variables are categorised to determine whether a distribution of scores is due to chance or experimental factors. (05 Mar 2000) |
| chi-square distribution | A distribution in which a variable is distributed like the sum of the the squares of any given independent random variable, each of which has a normal distribution with mean of zero and variance of one. The chi-square test is a statistical test based on comparison of a test statistic to a chi-square distribution. The oldest of these tests are used to detect whether two or more population distributions differ from one another. (12 Dec 1998) |
| chi-square test | A statistical method of assessing the significance of a difference, as when the data from two or more samples is represented by a discrete number such as the numbers of females and males attending each of two colleges. Synonym: x2 test. (05 Mar 2000) |

| square matrix | A matrix in which the numbers of rows and columns are equal. (05 Mar 2000) |
| square wave stimuli | Electrical stimulation in which the intensity of the current is brought suddenly to a given level and maintained at that level until it suddenly is cut off; this type of stimulus is particularly useful in obtaining a strength-duration curve. (05 Mar 2000) |
