What is the arithmetic mean?

The arithmetic mean is the average of a set of numbers, calculated by summing all values and dividing by the count.

How is arithmetic mean different from median and mode?

Mean is the sum divided by count (sensitive to outliers). Median is the middle value. Mode is the most frequent value.

Use it for symmetric data without extreme outliers, like average test scores or temperatures.

Arithmetic & Geometric Means

Data (comma-separated numbers)

The arithmetic mean (average) is the sum of values divided by the number of values.

mean = (x₁ + x₂ + … + xₙ) / n

For values 4, 7, 9 the mean is (4 + 7 + 9) / 3 = 6.67.

Sensitive to outliers?
Yes, large or small values can skew the mean.

Alternatives?
Median and trimmed means reduce outlier effects.
