The phrase "affecting the variability of" is correct and usable in written English.
It can be used in contexts where you are discussing factors that influence or change the variability of a particular subject or phenomenon.
Example: "The new environmental policies are affecting the variability of local weather patterns."
Alternatives: "influencing the variability of" or "modifying the variability of".
The analysis identified which categorical or situational variables were most affecting the variability of output quality.
Finally, the variable radiation environment in the SPECT camera room may also be a factor affecting the variability of the calibration factor measurement.
The stable pattern for Stands 3 and 4 also shows that the errors in GNSS accuracy affecting the variability of the stocking rate may be negligible at this level of resolution.
This study investigated the factors affecting the variability of the calibration factor estimated using a method based on planar imaging of a small in-air calibration source, a method applied clinically for planar dosimetry in a number of therapy applications.
To test for factors affecting the variability of the Sport and Recreation Function we checked for the impact of disease disability (HAQ score above median), older age, gender and disease duration.
In both cases, it is determined that the null hypothesis is rejected, and that all of the independent variables affect the variability of the dependent variable.
Current velocity affects the variability of seepage measurements; seepage standard deviation increased from ∼2 to ∼6 cm d−1 as current velocity increased from 9 to 65 cm s−1.
We characterise the probability distributions of wall strength and examine how spatial variability in unit flexural bond strength affects the variability of base cracking load, mid-height cracking load, peak load and behaviour of clay brick URM walls.
We evaluated the repeatability of this method and studied the factors that affect the variability of the resulting calibration factor.
Table 10 Study of the factors and their interactions that affect the variability of the measured Indirect tensile strength values in the group two of experimentsa.
