👉 Arithmetic mean, or simply "arg math," is a method of calculating the central tendency of a set of numbers by finding their average. It's computed by summing all the values in the dataset and then dividing that total by the number of values. For example, if you have a list of numbers {2, 4, 6, 8}, the arithmetic mean is (2+4+6+8)/4 = 5. This measure provides a basic understanding of the "typical" value within the dataset, though it can be sensitive to outliers, which might skew the result. Despite this limitation, the arithmetic mean is widely used due to its simplicity and effectiveness in many practical scenarios.
