The phrase "an absolute variation" is correct and usable in written English.
It can be used in contexts discussing changes or differences that are complete or total in nature, often in fields like mathematics, statistics, or philosophy.
Example: "The study revealed an absolute variation in the results, indicating a significant shift in the data trends."
Alternatives: "a complete change" or "a total difference".
For change in patients' weight, we anticipated a power of 90% to detect an expected absolute variation of mean change in weight of 2 (SD 7.4) kg between the usual care and standardised consultation groups with α=0.025, so 362 rheumatologists would be needed.
A large variability of optimal AVD was observed over time, with an average absolute variation of 20.6 ± 16 ms. Moreover, Brenyo et al. reported short values for optimal AVD (<100 ms) that were associated with a greater reduction in LV end-systolic volume (LVESV).
Two key aspects of behavioral consistency are among-individual differences (i.e., the extent to which an individual is reliably different from other individuals) and the absolute variation (or lack of variation) in a trait over time within individuals (also known as repeatability and stability; David et al. 2012).
The designed fiber offers ultraflattened negative dispersion in the near-infrared to most widely used S to L wavelength bands and average dispersion of about −138 ps/(nm km) with an absolute dispersion variation of 12 ps/(nm km).
Using this procedure an absolute TEC variation over single station is calculated.
The lower sub-row contains the results of an absolute parameter variation of plus and minus 1 (column 2).
The same absolute variation of ±1 for all input parameters results in a similar low variation of the total additional payment surplus (column 7 and 8).
This demonstrates how a visually tight regression fit, and high R2 values in regressions hide substantial absolute variation in our data.
Multi-scale geospatial and absolute variation of surface and near-surface soil physical and chemical properties can be mapped and quantified by coupling digital soil mapping techniques with high resolution remote sensing products.
