2-sample-t/process costs: The box (-plot) represents the mean 50% of the values, the upper and lower orthogonal line (called whisker) the 25% of the superior and lower values. The line drawn through the box demonstrates the median values. The outliers are displayed with asterisks. The line between the ACTUALcost and NOMINALcost links the mean values, the symbols in the charts stand for the mean value of all samples, which serves as an estimate for m.
