A fundamental concept in representing any of the outputs from a production process is that of a distribution distributions arise because any manufacturing process output will not yield the same value every time it is measured histogram: probability plot. Histogram definition, a graph of a frequency distribution in which rectangles with bases on the horizontal axis are given widths equal to the class intervals and heights equal to the corresponding frequencies see more.
