Clearly, if the whole loss of water is considered (by adding
the amount lost during the pre-drying step), the relationship
between both fractions is still maintained. However,
associated data points would not follow any more a trend
line along with the other two samples, but a new one displaced
downwards, making evident the overall reduction
in oil uptake.
Finally, it is interesting to note that when the whole set
of data is analyzed using simple regression (linear model), a
R2 = 93.92% is obtained, denoting the good relationship
between both fractions.
