WebExcel has a simple implementation of this e.g. to get the t-score for a sample of 1000, where I need to be 95% confident I would use: =TINV (0.05,999) and get the score ~1.96. Here is the code that I have used to implement confidence intervals so far, as you can see I am using a very crude way of getting the t-score at present (just allowing a ...

WebJan 31, 2024 · When to use a t test. A t test can only be used when comparing the means of two groups (a.k.a. pairwise comparison). If you want to compare more than two groups, or if you want to do multiple pairwise comparisons, use an ANOVA test or a post-hoc test.. The t test is a parametric test of difference, meaning that it makes the same assumptions … Webt score = -1 / 0.158114. t score = -6.325. Now, you will need to determine the degrees of freedom (df).
