WebNov 30, 2024 · Suppose we got a t statistic of 1.96. For two-sided test, the p-value is by definition the area further than this statistic in both directions, i.e., the area of "less than -1.96 or more than 1.96", which happens to be 0.05; this is the p-value when we do a two-sided test. On the other hand, for one-sided test, the p-value is by definition the ... marist college scholarships
