Good agreement and proximity to predicted and experimental results and high dye adsorption capacity in a short period of time confirm the high ability of the current wastewater treatment method, while a simple separation of existing nanoparticles and good regeneration support a good applicability of Fe3O4-MNPs-AC for wastewater treatment. Comparing the results of the four observers simultaneously on the basis of Fleiss kappa statistics, the proximity of the agreement with MSh TSE was better than with SSh EPI; No significant differences were observed in patients by primary or recurrent chole atoms and by age or sex. The accuracy of the analysis method is the proximity of the match between a real value and the value obtained. In accordance with ISO 5725-1, the general term “precision” is used to describe the proximity of a measurement to the actual value. When the term is applied to series of measurements of the same measurement, it is a component of random errors and a component of systematic errors. In this case, the veracity is the proximity of the average of a set of measurement results to the actual value and the accuracy is the agreement between a number of results. In the fields of science and technology, the accuracy of a measurement system is the degree of proximity of measurements from a quantity to the actual value of that quantity.  The accuracy of a measurement system that relates to reproducibility and repeatability is the degree to which repeated measurements under unchanged conditions show the same results.   Although the two words are commonly synonymous with precision and precision, they are deliberately contrasted in the context of the scientific method. Reproducibility can be defined as the proximity of the agreement between independent results obtained with the same process on the test equipment, but under different conditions, in this case in different experiments.
When measuring a set, accuracy is the proximity of the measurements to a given value, while accuracy is the proximity of the measurements. The proximity of the agreement or disagreement between these results is discussed in this paper. On the military level, precision refers primarily to the accuracy of the fire (shooting accuracy), the accuracy of the fire, expressed by the proximity of a group of fire on and around the center of the target.  A value of 8,000 m, with subsequent zeros and no decimal point, is ambiguous; the following zeros can be considered significant numbers or not. To avoid this ambiguity, the figure could be presented in the scientific notation: 8.0 × 103 m indicates that the first zero is significant (thus a margin of 50 m), while 8,000 × 103 m indicates that the three zeroes are significant, giving a margin of 0.5 m. Similarly, a multiple of the basic unit of measurement can be used: 8.0 km corresponds to 8.0 × 103 m. It indicates a margin of 0.05 km (50 m). However, trust in this convention can lead to false accuracy errors if data from non-compliant sources is accepted.
