An online probability calculator, such as Stat Trek's Normal Distribution Calculator. A normal distribution probability table (found in the appendix of most introductory statistics texts).In the examples below, we use Stat Trek's Normal Distribution Calculator to calculate probability. In the next ...
Then, using an online calculator, a handheld graphing calculator, or the standard normal distribution table, we find the cumulative probability associated with the z-score. For this problem, we will use Stat Trek's freenormal distribution calculator. Since every standard normal distribution has a ...

Normal Distribution The normal distribution is described by themean(μ) and thestandard deviation(σ). The normal distribution is often referred to as a 'bell curve' because of it's shape: Most of the values are around the center (μ) ...
In the past, when computers were not widely available, people used to look up the values of in normal distribution tables, where was tabulated for several values of . A normal distribution table looks something like this: zF(z)zF(z)zF(z) 0.00 0.5000 1.00 0.8413 2.00 0.9772 0.05 0.5199 ...
