Normal Distribution

Normal Distribution

A probability distribution shows what should happen, theoretically, based on the probability of a particular event.  There are numerous types of probability distributions.  The most important of all probability distributions is the normal distribution, which is bell-shaped and symmetric.  You see the "bell" curve in almost all disciplines.  Some of the included disciplines are psychology, business, economics, the sciences, nursing, and of course, mathematics.   Some of your instructors may use the normal distribution to help determine your grade ("grading on the curve").  The normal distribution is an extremely important concept that will be used throughout the remainder of this course.
