Statistics - Standard normal table

Standard Normal Table

Z 是标准正态随机变量。Z 的表格值为 z 处的累积正态分布的值。这是左尾正态分布表。随着 z 值的增加，正态分布表值也会增加。例如，Z=1.96 的值为 P (Z < 1.96) = .9750。

Z is the standard normal random variable. The table value for Z is the value of the cumulative normal distribution at z. This is the left-tailed normal table. As z-value increases, the normal table value also increases. For example, the value for Z=1.96 is P (Z < 1.96) = .9750.
