Sum of squared deviations from the mean.

Syntax

v = devsq(number1, number2, ...)

Returns sum((x - mean(x))^2) — the total squared deviation. Used internally in variance computations; rarely needed directly except for educational or specific statistical use.

Example

devsq(1, 2, 3, 4, 5)    % 10
