The analysis compares the measurement increment to the probable error to determine whether the measurement increment is appropriate. By default, the analysis calculates the measurement increment from the data. When the analysis determines the increment and the measurements have decimals, the increment is 1 unit of the least, non-zero, place value in the measurements. For example, for the values 1.100, 1.400, and 1.900, the increment is 0.1. If the measurements do not have decimals, the analysis uses an increment of 1.
To report a valid conclusion in the results, specify the increment if the measurement increment from the data is inaccurate. For example, the gage that you use reports results in the tenths place, but records measurements only to the nearest half, such as 1.0 and 1.5. Then, specify that the increment is 0.5.
