文中案例参考了Courtney K. Taylor的文章《How to Use the NORM.INV Function in Excel》在使用Excel统计概率的时候经常需要用到NORMINV函数功能。比如以x表示一个呈正态分布的随机变量,可能会被问到这样一个问题,x的数值等于多少才能在其整个概率分布中位于最低的10%?
mean, standard_dev, TRUE) = probability. Thus, precision of NORMINV depends on precision of NORMDIST. NORMINV uses an iterative search technique. If the search has not converged after 100 iterations, the function returns the #N/A error value. ...
1、 在Excel中输入NORMINV(10%,100,15),结果约等于80.78,该结果意味着小于等于80.78的智商值在全部智商值中为最低的10%; 2、 这个问题稍有点难。根据定义,NORMINV函数的计算结果体现的是概率分布曲线左侧的分布情况,如果想了解概率分布中最高部分的情况,需要看概率分布曲线右侧的分布情况。分布曲线中最高的1%所对...
Excel NORM.INV 函数 NORM.INV 函数用于计算并返回给定算术平均值和标准差的正态累积分布的反函数值。 Excel NORM.S.INV 函数 NORM.S.INV 函数用于计算并返回具有算术平均值为 0 和标准差为 1 的标准正态累积分布的反函数值,给定概率作为参数。 Excel NORM.DIST 函数 ...
Note: NORMINV has been replaced withNORM.INV. Although NORMINV is still available in current versions of Excel, you should consider using the new function from now on, because NORMINV may not be available in Excel’s future versions.
This function has been replaced with one or more new functions that may provide improved accuracy and whose names better reflect their usage. This function is still available for compatibility with earlier versions of Excel. However, if backward compatibility is not required, you should consider usin...
This function is still available for compatibility with earlier versions of Excel. However, if backward compatibility is not required, you should consider using the new functions from now on, because they more accurately describe their functionality.
