(1) H = log2(n + 1).
\n(2) H = \u03a3 pi log2(1\/pi + 1).<\/p>\n

H = the information-theoretic entropy of a decision.
\nn = the number of equally probable alternatives.
\npi = the probability of alternative i for n alternatives of unequal probability.<\/p>\n

The time it takes to make a decision is roughly proportional to H, the entropy of the decision (the log of the number of alternatives), i.e. T = k H, where k ~ 150 msec.<\/p>\n

This can be used to make a time estimate for how long people will take to make a decision in using a user interface, such as choosing a menu item, choosing a tool, or selecting an item on a navigation bar. Cognitive modeling approaches such as GOMS apply this to making predictions of human performance.<\/p>\n","protected":false},"excerpt":{"rendered":"
