Definition of the arithmetic mean
Definition of the arithmetic mean
- The arithmetic mean is a measure of central tendency a value around which the data gather and which represents them in general. We calculate it with the rule:
- Arithmetic mean = sum of the values ÷ number of values
- If the values are x1, x2, …, xn, then the mean = (x1 + x2 + … + xn) ÷ n.
- The arithmetic mean always lies between the smallest value and the largest value of the set.
