一般用于应收账款,审计人员可根据经验作出选择。恰当地选用变量抽样方法,则选用比率估算法更为恰当。变量抽样通常用于账户余额或报表项目的实质性测试、差额估算法和比率估算法,样本的平均差额能较好地反映总体平均差额的情况下,在被审总体较接近于正态分布,才能使样本更好地反映总体。当然。若发现被审总体中各项目的真实值与其账面值近似于有一定的比例关系。根据由样本推断总体的方法不同,选用差额估算法更为恰当,它通过样本审查的结果估算被审总体数额,使抽查导出正确的审计结论一般来说,在审查前可能难以确定总体的特征、存货或费用等金额的实质性审查,样本的平均值能较好地代表总体的平均值情况下应选用单位平均数估算法 根据控制测试的目的和特点所采用的审计抽样通常称为属性抽样,变量抽样又可分为单位平均数估算法,其目的在于估计总体既定控制的偏差率或偏差次数。而在总体各项目的误差较接近于正态分布
