(the average) - the sum of all data values divided by the number of the data values. deviation. - the difference between a data value in a set and the mean of the set. - the mean (average) of all deviations in a set equals zero. absolute value. - the distance (a positive quantity) of any value on a number line from zero. - the sum of the absolute values of deviations on each side of the mean are equal.
The differences between the electrical conductivity ratios of the solutions made from the various potassium chloride reagents were equivalent to about 0.0012 in salinity. The solution may not actually become a standard for salinity measurements even if it is prepared exactly according to the present definition.he differences between the electrical conductivity ratios of the solutions made from the various potassium chloride reagents were equivalent to about 0.0012 in salinity.

An understanding of these variations will enable the conductivity instrument user to obtain greater accuracy and repeatability. This paper. will explain the basics of the measurement, discuss the variables, and then suggest methods for use and calibration that will enhance accuracy. itive sodium ions will move toward. the negative voltage, the negative. chloride ions will move toward the. positive voltage, and current flow. will occur.
