Coba jelasin Aritmetik Mean dari Mean dalam bahasa sunda dong

The arithmetic mean is the "standard" average, often simply called the "mean". It is used for many purposes  but also often abused by incorrectly using it to describe skewed distributions, with highly misléading results. The classic example is average income - using the arithmetic méan makes it appéar to be much higher than is in fact the case. Consider the scores {1, 2, 2, 2, 3, 9}. The arithmetic méan is 3.16, but five out of six scores are below this!
