求翻译：Standard Deviation，也称mean square error，它是各数据偏离平均数的距离的平均数，它是离均差平方和平均后的方根，用σ表示。标准差是方差的算术平方根。标准差能反映一个数据集的离散程度。平均数相同的，标准差未必相同。是什么意思？

Standard Deviation, also known as mean square error, it is the deviation from the average distance of the data average, it is the deviation from average and average square after square root, with σ said. Arithmetic standard deviation is the square root of the variance. Standard deviation reflects th

Standard Deviation, also known as mean square error, it is a deviation from the average of the data, the average distance away from it is after all an average rates Square and the root mean square, used to be said. standard deviation is the square root of numeracy rates. standard deviation of a data

Standard Deviation, also called mean square error, it is various data deviation mean value distance mean value, it is after the divided difference sum of squares average root, with sigma expressed.The standard deviation is the variance arithmetic square root.The standard deviation can reflect a data

Standard Deviation, also known as the mean square error, it is the data deviate from the average distance of average, it is the square root of sum of squares of deviation from average after average, represented by σ. Standard deviation is the square root of the variance. Standard deviation reflects

Standard Deviation, call mean square error too, it is the average that all data deviate from the distance of averages, it is the square of deviation from average and root after being average, indicated by σ. The standard deviation is the arithmetic square root of the variance. The standard deviation
