The phrase "a negative deviation of" is correct and usable in written English.
It can be used in contexts such as statistics, finance, or quality control to describe a situation where a value is lower than a reference point or expected value.
Example: "The report indicated a negative deviation of 10% from the projected sales figures."
Alternatives: "a downward deviation of" or "a shortfall of".
Thus, there was a negative deviation of the order of 20 40% at the equatorial anomaly stations lying in this 'inhibited EIA region'.
This figure also shows that a negative deviation of the PLE leads to a greater RMSE than a positive error.
A negative deviation of the temperature is then associated with the negative R. We understand that S4 enhancement is associated with a high correlation in both the positive and negative directions.
A negative deviation of apparent Tm is therefore expected.
IHIC showed a negative deviation of 17.2%, quantitatively the most important.
From the analysis of 129Xe NMR chemical shifts, it is found that the mean volume of individual microvoids varies with a negative deviation against volume fraction of PPO in the blend.
Both theoretical and experimental partial molar quantities alike showed a negative deviation from those quantities of the ideal solution below (1−δ)=0.5 and a positive deviation above (1−δ)=0.5.
However, this result was caused by a strong negative deviation of one single mixture of six species.
From the results of the positron annihilation analysis (PALS) on the intermolecular free volume through the entire composition ratio, the TMBPS-PAr/PVC blend resulted in a larger negative deviation of the ortho-positronium (o-Ps) pick-off lifetimes (τ3) and the free cavity sizes (R) from linear additivity of those parameters of component polymers compared to the BPS-PAr/PVC blend.
A large negative deviation of Aex, together with the minimum value of ΔGex, was observed when the mole fraction of BSA (XBSA) was 0.8, indicating this to be the most stable mixture.
Deviation between the tissue surface of the wax denture and the plaster cast was shown in Figure 2, the green area represents a good fit between them, yellow and red areas indicate a positive deviation (tissue surface locating above the cast surface), and the blue area indicates the presence of a negative deviation (tissue surface locating below the cast surface).
