Using Q-function

  1. Jul 8, 2008 #1
    How can I compute values for the Q-function:

    Probability that a gaussian random variable with zero mean and some variance exceeds a particular value.



    Web, Calculator, Pencil???!

    Look it up on a table of the Normal distribution comes to mind. But I'm sure there are calculators that will also do that.

    A normal distribution table is here:

    Here's a site that does that automatically:
