Determining the Total Dispersion Zone for Micrometer S_M Measuring Equipment

The aim of the total dispersion zone for measuring equipment S_M is to define if three workers A, B, C can achieve the same values of measurement using the same measuring equipment. Before estimating the total dispersion zone for measuring equipment S_M. the calibration of the micrometer was carried out. The values were obtained by measuring the width of clip anchor. It is necessary to calculate the average values X_A, X_B, X _C and to calculate standard deviations S_ΔA, S_ΔB, S_ΔC for three workers. Finally, the total dispersion zone SM will be calculated and the results will be interpreted.
