(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.

Think about the arrangement of ions in solid calcium chloride and the ions in a solution of calcium chloride.In solid calcium chloride the atoms are arranged in a lattice structure, similar to that of sodium chloride.The atoms are in fixed positions and so cannot move to carry charge throughout the structure, which is what electrical conductivity is.Solid calcium chloride does not conduct electricity. An aqueous solution of calcium chloride does conduct. Explain the different conductivities of solid and aqueous calcium chloride.' (2 marks). Thanks, Dan.
