Given a set of n numbers, the average is the sum of the set of numbers divided by n. An average implies that I have a set of data and I've made the calculation as above. The word "normal" is usually used as "normal distribution." Two terms often confused are "mean" and "average." When an average (a statistic) is calculated, this is the best estimate of the mean (a parameter) of the distribution. If I am referring to the properties of a distribution, I should use the term "mean" and not "average." Often, people will refer to the mean of a dataset, when they have calculated an average.
