The phrase "a deviation from the expected" is correct and usable in written English.
It can be used in contexts where something does not align with what was anticipated or predicted.
Example: "The results of the experiment showed a deviation from the expected outcomes, prompting further investigation."
Alternatives: "a departure from the norm" or "a divergence from what was anticipated."
This observation indicates a deviation from the expected Rayleigh fractionation with distance and altitude (Dansgaard 1964; Coplen et al. 2000).
We give an example of a deviation from the expected thermodynamical behavior for the probe set 1091_at due to annotation problems, i.e., the surface-bound probe is not the exact complement of the target RNA sequence, because of errors present in public databases at the time when the array was designed.
We saw evidence of a deviation from the expected P-value distribution in the original analysis.
To assess this, we test for a deviation from the expected 1 1 ratio of phenotype classes.
The phenomenon of segregation distortion (SD), defined as a deviation from the expected Mendelian segregation ratios in a segregating population, has been reported in several crops.
Each marker was tested for a deviation from the expected ratio of 1 1 of parental alleles by using χ-tests after Yates and Bonferroni corrections.
Chi-squared analyses were then used to determine a) deviations from the expected sex ratio in fish sampled from the different risk categories, and b) differences in the proportions of "male" fish with oocytes within their testes, feminized ducts, and/or multiple sperm ducts between different sampling sites and between different risk categories.
Qu et al. [J Mater Res 2004 19 3423] have explained such behaviour as a deviation from the ISE expected for conical or pyramidal indenters (a H2 − 1/h proportionality) because of the rounded shape of real tips.
A high level of gene flow between populations A and B caused a deviation from the relationship expected under an IBD model.
For all five MYH7 missense mutations studied, we found a deviation from the usually expected equimolar ratio of wild-type versus mutated β-MHC.
The discrepancy between scores from two tasks observed for an individual patient is tested for a significant deviation from the expected discrepancy in a control sample.
