WebWe can now draw the power/sensitivity curve for the design and test, given all the potential, hypothetical effect sizes (shown in the figure to the left, as curve “A”). A “power analysis” is simply noting the features of this curve (perhaps along with changing the potential design by increasing N). Look at curve A.

WebFeb 20, 2024 · ANCOVA is not more powerful than a paired t-test as you originally said, it is simply that if the change from baseline is not constant in the treatment / control groups respectively, ANCOVA is more robust to detect an effect than a paired t-test.. You will often find in power/sample size calculations that you are dealing with simplified modeling … WebMultiple testing procedures ( MTP s) are statistical procedures that counteract this problem by adjusting p-values for effect estimates upward. Without the use of an MTP, the probability of false positive findings increases, sometimes dramatically, with the number of tests. Yet the use of an MTP can result in a substantial change in statistical ...
