One of the most familiar continuous probability distributions is the normal distribution as shown in Figure 2.  The normal distribution is also known as the Gaussian distribution or the bell curve. It is a very common distribution in nature and statistics and is based on the central tendency theory.  This is a situation where most items in a group tend towards the average and the further away from the average an event is the less likely it is to occur.
