The phrase "amplitude of variability" is correct and usable in written English.
It can be used in contexts discussing the range or extent of variation in a particular dataset or phenomenon.
Example: "The amplitude of variability in the test results indicates significant differences among the subjects."
Alternatives: "degree of variability" or "extent of variation".
The amplitude of variability depends on a number of source parameters, including luminosity and spectral properties.
Mean double amplitude of variability of diastolic blood pressure was correlated with the analogous variability of systolic blood pressure [r = 0.80] and pulse pressure was correlated with 7-day mean heart rate [r = 0.51].
Figure 3 shows the amplitude of variability associated with SPG changes (in SST) diagnosed from composite differences in (June, July, and August) between warm and cold SPG decades for surface temperature, mean sea level pressure, and precipitation.
Variability is thus a characteristic of any star whose evolution carries it to a certain size and luminosity, although the amplitude of the variability can vary dramatically.
Interestingly, the multivariate analysis indicated that the frequency of hypoglycaemia and the amplitude of glucose variability were correlated and represented predictors of poor prognosis.
The calculation of the standard deviation of the signal provides a measure of amplitude variability of the CP around the mean position.
Large amplitudes of interannual variability in surface aerosol concentrations reaching 20 30% relative to the 10-year averages were found over southern CEC in summer and over northern CEC in winter.
Due to intervals in observational time, the location of variable stars on color-color, and color-magnitude, diagrams will be biased by an additional scatter, because of changes in amplitudes and phases of variability.
At this time, the amplitude of orbital-scale variability further increased alongside a trend toward slightly increased magnetic susceptibility.
If the amplitude of the MJO variability is high, it is considered that the impacts of MJO on TCG should be significant even compared to those of ENSO.
The peak amplitude of the SSS variability associated with the Congo River discharge exceeds 3.0 psu, significantly greater than the designed Aquarius SSS retrieval accuracy of 0.2 psu.
