The arithmetic average, commonly known as the mean, is a key principle in the realm of statistics. You calculate it by summing up all the numbers in a given dataset and then dividing by the total number of values. This offers a central or 'average' data point. However, caution is required as it's highly sensitive to anomalies or skewed data distributions, which can significantly alter its value.
