The T Statistic is a definitive measure of significance
The significance level, denoted by alpha (α), is the maximum probability of rejecting the null hypothesis when it's actually true. Common significance levels are 0.05 and 0.01.

This is not accurate. The t statistic is just one measure of statistical significance, and the results should be interpreted in conjunction with other factors, such as the effect size and the sample size.
How the T Statistic Works
Common Questions
How do I determine the degrees of freedom?
t = (mean1 - mean2) / (standard error of the mean)
Common Misconceptions
The degrees of freedom for the t statistic depend on the sample size and the type of test being performed. In general, the degrees of freedom are equal to the sample size minus one (n-1).
