Normally distributed data assumes that about 68% of the values in the sample are within 1 standard deviation of the mean.
正态分布数据认为,样本中约68%的数值分布在距离平均值为1的标准偏差之内。
Conclusion:In the condition of unrepeated measurement, the variability between interviewers can be estimated by fitting two level variance component model for normally distributed data.
结论:对于问卷项目的应答为连续性正态分布的数据,在拟合重复调查的情形下,可以采用两水平方差成份模型评价问卷项目应答的信度。
For example, one may need to generate samples drawn from a normally distributed population or may need to compute the standard deviation of a large data set or plot a histogram.
例如,可能需要自常态分配数量之产生样本或需要计算大量资料的标准差或绘制直方图。
