Regression and dilution
* Regression dilution
Regression dilution arises if we are interested in the relationship between y and x, but estimate the relationship between y and w. Because w is measured with variability, the gradient of a regression line of y on w is less than the regression line of y on x.
Regression dilution was first mentioned, under the name attenuation, by Spearman ( 1904 ).

the cause of failure of Ostwald's dilution law in the case of strong electrolytes is due to the following factors "
( i ) The law is based on the fact that only a portion of the electrolyte is dissociated into ions at ordinary dilution and completely at infinite dilution.
