WebA t -score (a.k.a. a t -value) is equivalent to the number of standard deviations away from the mean of the t -distribution. The t -score is the test statistic used in t -tests and regression tests. It can also be used to describe how far from the mean an observation is when the data follow a t -distribution.

There are several varieties of t-tests. A one-sample t-test compares the mean of a sample with a hypothesized mean. An independent samples t-test looks at whether the means of two different samples have similar values.

WebAs such, very large sample sizes are likely to reject, even when the sample mean is very close to the hypothesized value. If this is a problem, it may be a hint that your interest lies more in an estimate of effect size (e.g. an estimate deviation of mean from hypothesized) than in an actual hypothesis test.
