**significance test power analysis**

The t-obtained would be the same for a one or twotailed test, but if you are doing a one-tailed test, you will have to look up the t-critical yourself to see if t-obtained is larger than t-critical. Alternatively, you can divide the significance by two to calculate the significance of a one-tailed test (as long as your effect is in the predicted direction).... It should be noted that there are two types of tests { one-tailed and two-tailed tests { which correspond to two di erent ways of computing the signi cance level (p-value). A two-tailed test considers any values that are extremes of the distribution to be of interest for the purposes of testing the hypothesis, irrespective of whether those values are particularly large or small. In contrast, a
