Calculate arithmetic mean, total sum, value count, minimum, and maximum of a numbers list.
Computes the arithmetic mean by summing all provided numbers (Σx) and dividing by the total count (n): Average = (x₁ + x₂ + ... + xn) / n. Also computes range and sample statistics.
Arithmetic Mean = (x₁ + x₂ + ... + xₙ) / nA student receives five test scores across a semester: 82, 90, 76, 94, and 88.
Interpretation: The student achieved a solid B+ grade average across all assessments.
In a dataset with [10, 0, 20], the average is 10 (30 / 3). Omitting the zero yields 15 (30 / 2), skewing the true mean.
In income or housing data, extreme billionaire incomes inflate the mean far above what typical people earn.
Add all the numbers together to find the total sum, then divide that sum by how many numbers there are.
