There are two strategies for doing that, squaring the values (which gives you the variance) and taking the absolute value (which gives you a thing called the Mean Absolute Deviation). T-test for Paired Samples - MathCracker.com It works for comparing independent samples, or for assessing if a sample belongs to a known population. We can combine means directly, but we can't do this with standard deviations. In order to have any hope of expressing this in terms of $s_x^2$ and $s_y^2$, we clearly need to decompose the sums of squares; for instance, $$(x_i - \bar z)^2 = (x_i - \bar x + \bar x - \bar z)^2 = (x_i - \bar x)^2 + 2(x_i - \bar x)(\bar x - \bar z) + (\bar x - \bar z)^2,$$ thus $$\sum_{i=1}^n (x_i - \bar z)^2 = (n-1)s_x^2 + 2(\bar x - \bar z)\sum_{i=1}^n (x_i - \bar x) + n(\bar x - \bar z)^2.$$ But the middle term vanishes, so this gives $$s_z^2 = \frac{(n-1)s_x^2 + n(\bar x - \bar z)^2 + (m-1)s_y^2 + m(\bar y - \bar z)^2}{n+m-1}.$$ Upon simplification, we find $$n(\bar x - \bar z)^2 + m(\bar y - \bar z)^2 = \frac{mn(\bar x - \bar y)^2}{m + n},$$ so the formula becomes $$s_z^2 = \frac{(n-1) s_x^2 + (m-1) s_y^2}{n+m-1} + \frac{nm(\bar x - \bar y)^2}{(n+m)(n+m-1)}.$$ This second term is the required correction factor.

Do roots of these polynomials approach the negative of the Euler-Mascheroni constant? I do not know the distribution of those samples, and I can't assume those are normal distributions. Even though taking the absolute value is being done by hand, it's easier to prove that the variance has a lot of pleasant properties that make a difference by the time you get to the end of the statistics playlist. This is a parametric test that should be used only if the normality assumption is met. From the class that I am in, my Professor has labeled this equation of finding standard deviation as the population standard deviation, which uses a different formula from the sample standard deviation. Does Counterspell prevent from any further spells being cast on a given turn? Pictured are two distributions of data, X 1 and X 2, with unknown means and standard deviations.The second panel shows the sampling distribution of the newly created random variable (X 1-X 2 X 1-X 2).This distribution is the theoretical distribution of many sample means from population 1 minus sample means from population 2.
