Excel统计函数——标准差Standard Deviation 本页说明如何使用 Excel 中的STDEV.P函数计算基于总体的标准差,以及如何使用Excel中的STDEV.S函数基于样本估计标准差。 什么是标准差? 标准差是一个数字,它告诉你数字与平均值之间的差距。 1. 例如,以下数字的平均值为 10。 解释:数字都是一样的,这意味着没有变化。因...
Explanation: the numbers are spread out. As a result, the numbers have a high standard deviation. STDEV.P The STDEV.P function (the P stands for Population) in Excel calculates the standard deviation based on the entire population. For example, you're teaching a group of 5 students. You ...
Sample standard deviationPopulation standard deviation √8.67= 2.94√7.43= 2.73 In Microsoft Excel, standard deviation is computed in the same way, but all of the above calculations are performed behind the scene. The key thing for you is to choose a proper standard deviation function, about whic...
OK, so we’ve got 2. This score is known as the “variance”, and it’s the base point for a lot of statistical tests, including the standard deviation. You can read more about the variance on its main page: how to calculate variance in Excel<<link>>. 5) Get the Square Root of...
1. STDEV.S (Sample Standard Deviation):This function calculates the standard deviation for a sample of data, assuming that the data represents only a portion of the entire population. Syntax:STDEV.S(number1, [number2], ...) Example: Suppose you have a sample of data in cells A1 to A10...
Standard deviation is a quantity representing the amount of dispersion. It refers to the deviation of a value from the mean of all values. The equation for measuring standard deviation is: √((∑(Xi-µ)²/n)) Xiis the i-th value of the entire population, ...
There is a table contains a sample data list in two columns B4:C8. To get the standard deviation of the sample, please use formula as below: =STDEV(B4:B8,C4:C8) Or you can directly type the data as an array in the formula
As you know, the Standard Error = Standard deviation / square root of total number of samples, therefore we can translate it to Excel formula asStandard Error = STDEV(sampling range)/SQRT(COUNT(sampling range)). For example, your sampling range is paced in the Range B1:G4 as below screen...
Standard deviation can be both, positive and negative. The closer the standard deviation is to 0, the lesser the variability in your data For example, if the mean of a data set is 70 and the standard deviation is 5. That’s fine. It means that most of the values in the dataset are...
Compatibility: Calculates standard deviation based on the entire population STDEVPA Statistical: Calculates standard deviation based on the entire population, including numbers, text, and logical values STEYX Statistical: Returns the standard error of the predicted y-value for each x in the regression...
