The phrase "a considerable deviation" is correct and usable in written English.
It can be used to describe a significant difference or divergence from a standard, norm, or expected outcome.
Example: "The results of the experiment showed a considerable deviation from the initial hypothesis, prompting further investigation."
Alternatives: "a significant divergence" or "a notable difference".
41% of patients showed a considerable deviation between early and late FET-PET.
A considerable deviation is found between the prediction by existing design-oriented confinement models and test results.
The solution shows that there is a considerable deviation between the exact solution and the simple quasi-steady solution.
In the case that the no-slip boundary condition was enforced in the calculations for the solid phase, the wall effect was significant and a considerable deviation between computed and experimentally observed bubble growth curves was found.
As this study showed a considerable deviation between natural and prosthetic groove orientation, an optimal prosthetic groove orientation, matching the average orientation in the natural knee, was mathematically determined.
At an initial glycerol concentration of 25 g/l the amount of dry cell mass of MNO24 was 3.5 times higher compared to the wild type on crude glycerol, however, with a considerable deviation.
That is a considerable difference.
In this paper, we show that changes to the original plan induced by a disruption may impose considerable deviation costs throughout the system.
Field blanks exposed to the atmosphere in a manner similar to the actual well water samples can be used to enumerate background levels caused by deposition of enteric bacteria in ambient air during the sampling process, for example, a field transfer sample: At our field sites, the geometric mean of the transfer blanks is 1.4 cfu/100 mL with a considerable standard deviation.
For a montmorillonitic loam, a montmorillonitic clay and a peat soil, considerable deviations were found between the conductivity ratio and the viscosity ratio; for the peat, which was also used in temperature experiments, no such deviations were observed at different temperatures.
Analytical results using a constant waste heat temperature or based on thermal efficiency may result in considerable deviation of system design relative to the varying temperature conditions of the actual waste heat recovery and is regarded as inappropriate.
