1、首先打开电脑里的excel软件，新建一个excel文档，输入需要进行处理的数据。2、然后需要选取放方差的单元格，并点击f(x)函数按钮。3、然后需要在函数框中找到“统计”选项，再找到“STDEVS”函数，点击“确定”。4、然后需要点击函数输入框在后面添加“^2”，再按回车。5、回车后即可在单元格内显示...
你不用excel的时候 是怎么算的？ 这个你要说清楚 然后告诉你 用excel 怎么算……
I am seeing an inconsistency in certain aspects of the literature concerning this test. I would like your input in this matter. In conducting a two tailed chi-squared test for a single population variance, it is clear that one computes the p value by doubling the smaller area on a side o...

In this article, the degrees of freedom of the sample variance are simulated by using the Visual Basic for Applications of Microsoft Excel 2010. The simulation file dynamically displays why the sample variance should be calculated by dividing the sum of squared deviations by ‐1 rather than , ...
There are many solutions to test for the equality (homogeneity) of variance across groups, including: F-test: Compare the variances of two samples. The data must be normally distributed. Bartlett’s test: Compare the variances of k samples, where k can be more than two samples. The data ...
Further, this formula reveals that altering the relative sample sizes for the strata (nh) will alter the variance of ȳst. In fact, for any fixed sample size, there exists a stratified random sampling strategy that yields an estimate of μ of minimum variance. This is known as stratificatio...

(this is also one of theAP Statistics formulas). However, if you’re finding the sample mean, you’re probably going to be finding other descriptive statistics, like thesample varianceor theinterquartile rangeso you may want to consider finding thesample mean in Excelor other technology. Why...
The variance estimators however show greater distinction. For a very small sample size (up to 15) the formula (16) is performing the best (within 10% of the real sample standard deviation). When the sample size is between 16 and 70, the formula Range/4 is the best estimator of the sam...
