Abstract
Calculations of most probable values on the basis of the equations y = a · x + b · x^2^, y/x = a + b · x and x = a^*^ + b^*^ · y/x have been carried out with data from solution viscometry, ebulliometry, and vapor pressure osmometry. The calculations carried out with the method of least squares give different coefficients for the equations taken as a basis. However equal coefficients are obtained with the method of Deming in which the measured data are weighted. Furthermore the so calculated slopes of the equations differ from those determined by the method of least squares whereby the differences depend upon the type of equations and upon the deviation of the measured data.
