(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.

Sodium chloride and potassium chloride are ionic compounds. Both are solids, where cations and anions are in a closed packed structure. Sodium and potassium are group 1 metals, which have the capability to make +1 cations. Chloride is the -1 anion made by group 7 element, chlorine.Since group 1 elements are electropositive and group seven elements are electronegative, their electronegativity difference is larger. So they form ionic bonds.odium and potassium are group 1 metals, which have the capability to make +1 cations. Chloride is the -1 anion made by group 7 element, chlorine.
