To standardize is made to make sure that every time we take the substance, it is the variance of the least compared with standards so that results from making trial every time with the same value.
To standardize is to ensure that every time we use it is a variant of the substances we prepare minimum standards with respect to the results of the experiment are the same every time.
The standardize is made to ensure that every time we use of it will have the variance of substances that we prepare a minimum by compared with the standard substance to yield from experiment to every time is same.
