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。
