What is Notes Dell about?
Sig (2 tailed) refers to the p-value in a t-statistic test, which is compared to the significance level alpha to determine if the null hypothesis can be rejected. For a one-tailed test, the p-value is divided by 2 and compared to alpha, while for a two-tailed test the full p-value is compared to alpha. When comparing more than two groups, analysis of variance (ANOVA) is used.
