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.

WebBasically, for small samples, the t-statistic is used. Z = X−μ σ t = ¯x −μ0 s √n, Z = X − μ σ t = x ¯ − μ 0 s n, The mean must be known prior to computing the sample variance. This places a restriction on sample variability such that only n-1 scores in a sample are free to vary.
