A t-score is the number of standard deviations from the mean in a t-distribution.You can typically look up a t-score in a t-table, or by using an online t-score calculator.. In statistics, t-scores are primarily used to find two things The upper and lower bounds of a confidence interval when the data are approximately normally distributed.
The t-test procedure performs t-tests for one sample, two samples and paired observations. The single-sample t-test compares the mean of the sample to a given number which you supply. The independent samples t-test compares the difference in the means from the two groups to a given value usually 0.
For a paired t-test, statistics programs usually display the sample mean-difference m A-B, which is just the mean of the differences between the members of the pairs, i.e. A i - B i . Along with this, as usual, are the statistic t , together with an associated degrees-of-freedom df , and the statistic p .

Jun 25, 2017 Hence there are only 10 subjects in this example. The sample mean difference is the same as that in Example 1. However, the example variance of the sample mean difference is 2.45. The paired t-test statistic equals 6.33. From the t-distribution with df 9, we obtain the p-value of 0.00007, which shows strong evidence to reject the null hypothesis.
