It could be normal, everything, that would be a Gaussian, where if you recall there was a mean, and a standard deviation, and most values were going to be close to the mean.

可能是正态分布，也就是高斯分布，只要有平均值和标准偏差值，你就可以进行调用，大部分的值都是集中在平均值附近的。

Statistics histogram data processing scheme is designed. Standard deviation of frequency modulation is found out according to normal distribution characteristics.

设计了统计直方图数据处理方案，按照正态分布的特性找出了寄生频率调制的标准偏差。

RANDN (n) is an N-by-N matrix with random entries, chosen from a normal distribution with mean zero, variance one and standard deviation one.

是一个n - n矩阵随机作品，选自正态分布均值为零，方差一个标准偏差为一。

Sure enough, using standard deviation of the returns, the day after Election Day is significantly more volatile than a normal day by about 80% (1.99% vs. 1.14%).
