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。因此,这些数字的标准偏差为零。STDEV ...
使用Excel中的STDEV.P函数计算基于总体的标准差，而STDEV.S函数则用于基于样本估计标准差。标准差是衡量数据与平均值差异的指标。数值接近平均值的标准差较低，而数值分散的标准差较高。STDEV.P函数计算整个人口的标准差。以一组5名学生为例，STDEV.P函数将使用以下公式计算标准差。1. 计算平均值。2. ...
STDEV.P：总体的标准差当你手握整个数据集，Excel的STDEV.P就像你的统计助手，使用公式 (∑(每个值 - 平均值)^2 / 总数据点数)^(1/2) 计算出基于全部数据的标准差。在教5名学生的例子中，通过计算每个成绩与平均分的距离，然后平方和除以总数，Excel能自动完成这项繁琐工作。STDEV.S：样本的标准...
In statistics, standard deviation is usually used for measuring the dispersion from the average. But in fact, to calculate standard deviation is a little complex, you need to get the average first, and then calculate the difference of each data point from the mean, and square the result of ...
To get a better idea of how this works, please have a look at the following data: For Biology, the standard deviation is 5 (rounded to an integer), which tells us that the majority of scores are no more than 5 points away from the mean. Is that good? Well, yes, it indicates that...
Standard Deviation Using Excel 1/25/2006 1. Input your data into a column in the Excel spread sheet. Chapter 2 prob. 6 Table 2-7 2. Put you cursor on a blank space in the spread sheet where you want the standard deviation to be placed, and then go to the function bar f(x) 3....
Calculate standard deviation using STDEV We know how impatient you’re getting to see the Excel standard deviation function in action. So here we go with the oldest function for calculating standard deviation in Excel. Below is the data for some people from a small town along with theirages ...
C. Stdevn(Stdev.S) and StdevA function difference: their difference is limited to how to deal with logical values and text values, for logical values and text values, if input directly into the list of argument, they are included in the calculation of standard deviation by Stdev function, ...
Excel has two built-in functions to calculate standard deviation: STDEV.S and STDEV.P. The STDEV.S function calculates the sample standard deviation, while the STDEV.P function calculates the population standard deviation.Here is how to calculate standard deviation in Excel:...
This page explains how to calculate the standard deviation based on the entire population using the STDEV.P function in Excel and how to estimate the standard deviation based on a sample using the STDEV.S function in Excel.
