Web15 okt. 2024 · To find the p-value we need two things, the t-test value (from step2) and the number of degrees of freedom that can be computed as follows df=n-2 (with n is the size of the sample). Having these two values we can compute the p-value by: Using a software Looking it up through the t-table Step 4: Decision Finally, we make a decision: WebThe interpretability of factors can be improved through rotation. Rotation maximizes the loading of each variable on one of the extracted factors whilst minimizing the loading on all other factors. Rotation works through changing the absolute values of the variables whilst keeping their differential values constant.
