Statistical T-Distribution — The “T-Table” - dummies
The first table, (Group Statistics) shows descriptive statistics for the two groups (low-stress and high-stress) separately.Note that the means for the two groups look somewhat different. This might be due to chance, so we will want to test this with the t test in the next table.

Statistical T-Distribution — The “T-Table” - dummies
34 rows · As a statistical tool, a t-table lists critical values for two-tailed tests. You then use these values to determine confidence values. The following t-table shows degrees of freedom for selected percentiles from the 90th to the 99th: Degrees of Freedom 90th Percentile (a = .10) 95th Percentile (a = .05) 97.5th Percentile (a = .025) […]
