Means Node Options

The Options tab enables you to set the threshold p values used to label results as important, marginal, or unimportant. You can also edit the label for each ranking. Importance is measured on a percentage scale and can be broadly defined as 1 minus the probability of obtaining a result (such as the difference in means between two fields) as extreme as or more extreme than the observed result by chance alone. For example, a p value greater than 0.95 indicates less than a 5% chance that the result could be explained by chance alone.

Importance labels. You can edit the labels used to label each field pair or group in the output. The default labels are important, marginal, and unimportant.

Cutoff values. Specifies the threshold for each rank. Typically p values greater than 0.95 would rank as important, while those lower than 0.9 would be unimportant, but these thresholds can be adjusted as needed.

Note: Importance measures are available in a number of nodes. The specific computations depend on the node and on the type of target and input fields used, but the values can still be compared, since all are measured on a percentage scale.
