Find mean from histogram
WebJul 31, 2024 · If the x values are bin edges, then the estimate of the mean contains an error equal to or less than +/-0.00025 which is half of the bin widths ( diff (x (:,1))/2 ). If the x values are bin edges and x (1) is the left edge of the first bin, then half the bin width must be added to each x-value to approximate the bin centers.
