Document Summary
An average is a number that describes a set of experimental observations. Most common averages are mean, median, and mode satisfying. The expected value is a number that describes the probability model of an experiment. Mode of random variable x is a number satisfying for all x. Median of random variable x is a number is the probability of x times its. Number in the middle of a data set. Equal number of data items above and below the median value. Adding up all x"s in the subspace of x gives the expected value. The bernoulli (p) random variable x has expected value e[x] = p. The geometric (p) random variable x has expected value e[x]=1/p. If probability of rejecting an integrated circuit is p = 1/5 then you have to perform. New section 1 page 1 circuit is p = 1/5 then you have to perform. E[y] = 1/p = 5 tests until first reject is observed.
