Unpooled Standard Error Formula at Mitchell Trigg blog

Unpooled Standard Error Formula. The computational formula for the pooled variance is: The formula for the standard error of the difference in two means is similar to the formula for other standard errors. The mathematics and theory are complicated for this. This calculator computes the unpooled variance and standard deviation for two given sample standard deviations s1 and s2, with sample sizes n1 and n2 When the assumption of equal variances is not valid, we need to use separate, or unpooled, variances. Pooled tests assumes that two populations have equal variances. Examining the standard error formula. Do you know the difference between pooled and unpooled?
