aStandard Deviation,也称mean square error,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。 Standard Deviation, also called mean square error, is various data deviation mean value dis...
Like STDEV, the STDEV.S function calculates the sample standard deviation of a set of values based on the classic sample standard deviation formula discussed in the previous section. Excel STDEVA function STDEVA(value1, [value2], …)is another function to calculate standard deviation of a sample...
Standard deviation is a statistical term that provides a good indication of volatility. It measures how widely values (closing prices for instance) are dispersed from the average. Dispersion is difference between the actual value (closing price) and the average value (mean closing price). The ...

the individual values visibly deviate from the average value, they do so in a way that appears random, and the deviations are small relative to the average value. When a statistician sees small, random deviations from the mean, an electrical engineer sees noise. Average Deviation Ho...

Good 15% - 12.5% = 2.5 6.25 X 40% = 2.5 So-So 5% - 12.5% = 7.5 56.25 X 30% = 16.875 Really Bad 0% - 12.5% = 12.5 156.25 X 10% = 15.625 Total = 66.25So the total is 66.25. This is called the Variance. The square root of 66.25 = 8.139 So the Standard Deviation is 8....
we are calculating the Sample Standard Deviation, so instead of dividing by how many (N), we will divide by N-1Example 2 (continued): Sum = 6.25 + 20.25 + 2.25 + 6.25 + 30.25 + 0.25 = 65.5 Divide by N-1: (1/5) × 65.5 = 13.1 (This value is called the "Sample Variance")...
Example of Standard Deviation Measurement For example, suppose a mutual fund achieves the following annual rates of return over the course of five years: 4%, 6%, 8.5%, 2%, and 4%. The mean value, or average, is 4.9%. The standard deviation is 2.46%. ...
