Mean Formula

The arithmetic mean (average) of n numbers is:

textMean=fracx1+x2+cdots+xnn=fracsumi=1nxin\\text{Mean} = \\frac{x_1 + x_2 + \\cdots + x_n}{n} = \\frac{\\sum_{i=1}^{n} x_i}{n}

Where x₁, x₂, ..., xₙ are the numbers and n is the count.

About the Mean

The mean is the most common measure of central tendency.

It represents the "average" value of a dataset.

The mean is sensitive to outliers (extreme values).

For a balanced dataset, the mean is at the center.
