Abstract
This paper introduces a new method which estimates the performance of workers on the work production, using the work achievement and the tendency equation which are derived from the mean of the data observed.
This method is an analytical method using a kind of ratio method. That is, the results of work are estimated by a work achievement Q which is a function of the ratio of variation δ, where δ is the dispersion of the data.
As an example of practical applications this paper shows the performance of individual press workers.
