 Hi, this is Dr. Don, and I know I sound a bit like a broken record when I keep saying use stat crunch instead of the tables. And it's better than most other sites that I found. Once you've got stat crunch open to find your probability, just go to stat, open up the calculators, and then pick the distribution that you're interested in. Most often, we're interested in the chi-square, the F foranovas, the normal, the Z, or the T. Let's look at the normal, again, because we use that more than anything else. You bring up the calculator, and it draws the nice sketch for you to show what's going on and to help you. It defaults to the standard normal distribution with a mean of zero and a standard deviation of one, which is what you need when you're trying to find test statistics probability, or standardized test statistics probability. You just, with the Z, you need to enter either a right tail or a left tail. Just use the right tail, which is quite common. And let's say our test statistic standardized was 2.2, and we just click compute, and we get a very small probability, because that's 2.2 standard deviations out of 0.014. It's that quick, and it's equally quick for the other distributions.
