3. VAR 和 VAR.S 产生完全相同的结果。 注意:Microsoft Excel 建议使用新的 VAR.S 函数。
方差是标准差的平方,用于解决统计问题时更为简便。VAR.P函数计算整个总体的方差,而VAR.S函数用于根据样本估计方差。注意,VAR和VAR.S函数的结果相同,Microsoft Excel建议使用新的VAR.S函数。
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...
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 Note that this is a sample drawn from ...
Standard deviation helps with that! Don’t worry if this sounds complicated—Excel makes it easy. In this guide, you’ll learn: What does standard deviation mean? The formula for standard deviation (don’t worry, Excel does the math). How to find standard deviation in Excel step-by-step....
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. Click on f(x)and select Statistical in...
Like the definitions, Microsoft Excel has two different functions to calculate standard deviation, depending on whether you are working with an entire population or a sample. STDEV.P() for population standard deviation TheSTDEV.P()function in Excel calculates the standard deviation for an entire pop...

昨天用excel的standard deviation函数计方差,结果一个后面有p,一个后面有s,一个计总体方差,一个计样本方差。啊,p和s到底代表什么呢,想了很久,才想起来是population和sample。今早,计算不同层级的分数比较,有三个层次,糟糕,t检验不能用了,要用什么,我已经完全忘记了世上还有oneway anova。完了。
