The phrase "added variability" is correct and usable in written English.
It can be used in contexts where you want to describe an increase in variability or diversity in a particular situation or dataset.
Example: "The new experimental design introduced added variability, which allowed for a more comprehensive analysis of the results."
Alternatives: "increased variability" or "additional variability".
A flexible inflation targeting regime is close to optimal only if the central bank balances inflation and value added variability.
The precision comparison in Fig. 5 indicates similar conclusion as Fig. 4 and the general pattern in these two figures is reflected in Figs. 6 and 7 but with added variability.
Moreover, we added variability in trajectories by changing the experimental protocol (tested and trained trajectories were not the same).
Finally, the age range of the subjects covers a period of significant brain development; although careful attention was paid to age-matching, the course of hippocampal development likely added variability to the measures.
Subsequently, we added variability parameters to the chosen TK model.
This may have added variability to our measures, but such sampling represents what occurs in clinical practice.
Manual tryptic digest and the subsequent clean-up steps can add variability even before the sample reaches the analytical platform.
While set within a larger scale framework in terms of geochemical features, supply with energy and nutrients, and exchange intensity and dynamics, the micro scale adds variability, by providing heterogeneous zones at the micro scale which enable a wider range of redox reactions.
Respiratory motion has been shown to add variability to measured texture parameters [25].
However, care in defining the region would be needed to avoid adding variability to the measurement.
Its whole value proposition is fresh, locally sourced ingredients, which necessarily adds variability to supply and therefore increases risk.
