Phys.), the average error of a number of observations found by taking the mean value of the positive and negative errors without regard to sign. Mean-square error, or Error of the mean square (Math. Phys.), the error the square of which is the mean of the squares of all the errors; -- called also, especially by European writers, mean error. Mean line. (Crystallog.) Same as Bisectrix.
