(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.

Even in solid state sodium chloride contains ion of sodium (Na+) and chloride (Cl-) ions arranged in a regular pattern. These ions are not very free to move about and their position is more or less fixed. On heating sodium chloride melts and it becomes liquid. The ions in liquid are more free to move about.The movement of ions helps to conduct electricity. (Note: for the same reason an aqueous solution of NaCl conducts electricity as NaCl ionizes to give Na+ and Cl-ions).n heating sodium chloride melts and it becomes liquid. The ions in liquid are more free to move about. The movement of ions helps to conduct electricity.
