Can someone explain the computational formula Excel uses for the two sample mean t-test for samples with unequal variances. I've attached all I can find from Excel. In particular what is delta sub o, m and n variables?? Thanks ...AndyCapture...
The first type of t-test considered is the simplest. One-Sample t-Test The one-sample t-test is used for comparing sample results with a known value. Specifically, in this type of test, a single sample is collected, and the resulting sample mean is compared with a value of interest, ...

The formula for a t-statistic for two population means (with two independent samples), with unknown population variances shows us how to calculate t-test with mean and standard deviation and it depends on whether the population variances are assumed to be equal or not. If the population varianc...
Two sample t-test is used to check whether the means of two groups are significantly different from each other. For example, if you want to see if mean weight of males and females have statistically significant difference between them. Independent T-test assumes that the two samples have ...
This chapter discuses two-sample t -tests. In a two-sample t -test, the samples are taken from two distinct populations. The chapter presents examples to explain the two-sample t -distribution. To find the mean vector nearest the observation vector, the concept of the orthogonal projection ...
