The phrase "an error of around" is correct and usable in written English.
It can be used when discussing an approximate measurement or estimation of an error in a specific context, such as statistics or calculations.
Example: "The experiment showed an error of around 5% in the final results."
Alternatives: "an approximate error of" or "an error of approximately".
Furthermore, the ratio between the 2-D and 1-D simulations, shown in Fig. 3b, gives a minimum value close to 40%, illustrating that the 1-D simulation can result in an error of around 60%.
Even if you only count the surveys done over the final week of the campaign, Obama's lead is 1.3pt; that'll be an error of around 2pt. Eliminating Gallup and Rasmussen put the final average up at 1.5pt, yet, that is also going to be perhaps up to 2pt biased against Obama.
By summing up each single error term, we suggest that our field-estimated AGB have an error of around 17%.
In step (a), the refractive index of the coating was determined as 1.506 ± 0.014 at 1550 nm, which is an error of around 1%.
To some extent this is mitigated against by a sensible user-entered threshold of around 20 ion counts, but even so, comparing two reporter ion peaks that just pass such threshold could introduce an error of around 2.5% into the final ratios: Eg. The user-entered ion count threshold is set to 19.
A 10-cm vertical or longitudinal offset both result in a translation error of around 6% (Figure 13, bottom two).
For each P value, 40 000 permutations were generated in order to obtain a standard error of around 0.001.
However, positional errors were greater for homes outside the large metropolitan areas (Bonner et al. 2003), and rural addresses in Iowa had a median positional error of around 200 meters (Ward et al. submitted).
On the average, we achieved a of around with low and errors of around, and respectively.
Based on classical schematic model eyes such as the Gullstrand eye, a measurement error of 1 mm in AL ends up in an error refraction of around 3.5 D and an erroneous determination of the pseudophakic lens position of 1 mm based on the preoperative assessed phakic ACD leads to an error refraction of around 1.6 D.
The comparison of M θ r curves (Figs. 16, 17) shows that the connection stiffness is highly overestimated by Frye Morris model and the proposed model agrees well with the numerical results with an average error of around 15%%.
