Where does the unexplained variance lie?
Of course, the effect of other body parameters may be hidden in the remaining unexplained variance.
Students' mathematics performance depends on multiple factors that contribute to a large proportion of unexplained variance.
Subjective factors could help in decreasing this proportion of unexplained variance.
Some of the unexplained variance can be attributed to measurement error, which is reflected by Cronbach's alpha reliability measures below unity.
The cross-classified multilevel model, which does not include any explanatory variables, gives the distribution of unexplained variance across three levels (model 0, Table 3).
The unexplained variance is attributed to differences in experimental set-ups and measuring errors which could not be explicitly accounted for due to a lack of additional data.
Using only input and output data, an RTD model explained sedimentation rates with less unexplained variance than the standard, plug-flow model.
The coefficient of adjusted r-squared for the recovery capability is 0.31, which suggests a significant amount of unexplained variance by the regression model.
These models incorporate regression coefficients that associate study characteristics (i.e., moderators) to study outcomes while allowing for unexplained variance in the model (Raudenbush [2009]).
However, the unexplained variance of the intention to remain at t4 (57%) also shows that there must be other explanatory factors.
