So how do we calculate the probability below a negative z-value (as illustrated below)?We start by remembering that the standard normal distribution has a total area (probability) equal to 1 and it is also symmetrical about the mean. Thus, we can do the following to calculate negative z-...

How to Find the Z-Score To use the z-score (sometimes called a standard score) to calculate this probability, you first must find the mean and standard deviation that defines the distribution. Then, calculate the z-score for a given raw score. You can do this using az-score calculatoror...
You can see a normal distribution being created by random chance! It is called the Quincunx and it is an amazing machine. Have a play with it!Standard DeviationsThe Standard Deviation is a measure of how spread out numbers are (read that page for details on how to calculate it)....
A normal distribution probability table (found in the appendix of most introductory statistics texts). In the examples below, we use Stat Trek'sNormal Distribution Calculatorto calculate probability. In the next lesson, we use normal distribution probability tables. ...
While most people are familiar with a normal distribution, they may not be as familiar with a log-normal distribution. A normal distribution can be converted to a log-normal distribution using logarithmic mathematics. That is primarily the basis as log-normal distributions can only come from a n...
