Typically, this is represented as an absolute value. The resolution of a measurement will limit the accuracy and precision. If the resolution of your equipment is low, you are unable to measure very small changes accurately or precisely. High resolution enables you to measure closer to the true...
试题来源: 解析 A。本题考查科技词汇的近义词。“precision”意思是精确,A 选项“accuracy”也是精确的意思,是“precision”的近义词;B 选项“imprecision”不精确;C 选项“roughness”粗糙;D 选项“approximation”近似值,均不是“precision”的近义词。反馈 收藏 ...
故填accuracy。 (8)题详解: 考查定语从句。句意:例如,在处理含有13000张图像的数据库时,算法的精确度达到95%,但在面对100万张图像时精确度下滑至70%左右。分析句子成分和句子结构可知,句子___ were right 95% of the time对前面的名词Algorithms起修饰限定作用,所以这是一个定语从句;分析定语从句句子成分可知...
The ubiquity of non-uniqueness in near-surface refraction seismology emphasises the importance of making a clear distinction between accuracy, that is, the validity of the model, and precision, that is, traveltime misfit errors. Non-uniqueness can be resolved by identifying the most probable model...
of the rim, she has a high degree of accuracy. If she doesn't make many baskets but always strikes the same portion of the rim, she has a high degree of precision. A player whose free throws always make the basket the exact same way has a high degree of both accuracy and precision...
【解析】The accuracy(精确性)of scientific observations and calcula-tions is always at the mercy of the scientists' time-keeping meth-od. For this reason, scientists are interested in the instrumentsthat give promise of more precise time-keeping.In their search for precision, scientists have turned...
What's the difference between accuracy and precision in measurements or data? Why is it important?This article defines the terms accuracy and precision as they are used to describe measurements of all kinds.Whether you are measuring electrical resistance, the comparative depth of stair treads, or ...
Precision and Accuracy:The following two terms are very essential while dealing with the data measurements. Precision Accuracy They are quite important for statistical purposes.Answer and Explanation: Accuracy and precision are the two essential ways by which we can judge our measurements. ...
Accuracy is defined as, "The ability of a measurement to match the actual value of the quantity being measured". If in reality it is 34.0 F outside and a temperature sensor reads 34.0 F, then than sensor is accurate. Precision is defined as, ...
-Accuracyrefers to how close a measurement is to the true or accepted value. It indicates the correctness of a measurement. Step 2: Define Precision -Precisionrefers to how close multiple measurements are to each other, regardless of whether they are close to the true value. It indicates the...
