(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.

Lesson Summary. Potassium chloride is an ionic compound and is a salt that naturally occurs as a solid that has a powdery and crystalline appearance. Its chemical formula is KCl: it consists of one potassium (K+) ion and one chlorine (Cl-) ion.Potassium chloride has so many uses in various fields.It is a main component of fertilizer, and in medicine, it treats a condition called hypokalemia, which results when potassium levels in blood are lower than normal.ere, we can see that KCl consists of a positive ion (K+) and a negative ion (Cl-). Salts are ionic compounds consisting of positive and negative ions. Because potassium chloride has ions of opposite charges, potassium chloride is classified as a salt.
