Accuracy,Precision,and Error Introduction to Chemistry

Accuracy and PrecisionErrorHow Do Accuracy,Precision,and Error Relate to Each other?Accuracy is how close a measurement is to the correct value for that measurement.The precision of a measurement system is refers to how close the agreement is between repeated measurements (which are repeated under the same conditions).Measurements can be both accurate and precise,accurate but not precise,precise but not accurate,or neither.Precision is sometimes separated into 1.Repeatability The variation arising when all efforts are made to keep conditions constant by using the samSee more on courses.lumenlearningPrecision (repeatability and reproducibility) studies and Precision (repeatability and reproducibility) studies and sample-size calculation McAlinden,Colm MB BCh,BSc (Hons),MSc,PhD; Khadka,Jyoti PhD; Pesudovs,Konrad PhD Journal of Cataract Refractive Surgery December 2015 - Volume 41 - Issue 12 - p 2598-2604Cited by 32Publish Year 2017Author Bernardo T.Lopes,Cynthia J.Roberts,Ahmed Elsheikh,Riccardo Vinciguerra,Paolo Vinciguerra,SvenRelated searches for precision repeatability and reproducibirepeatability and reproducibility pdfrepeatability and reproducibility studyrepeatability and reproducibility examplesgauge repeatability and reproducibilityrepeatability and reproducibility formularepeatability and reproducibility excelrepeatability and reproducibility calculationgage repeatability reproducibilitySome results are removed in response to a notice of local law requirement.For more information,please see here.12345NextCited by 34Publish Year 2018Author Velicia Bachtiar,Matthew D.Kelly,Henry R.Wilman,Jaco Jacobs,Rexford Newbould,Catherine J.KelEstimated Reading Time 6 minsDevelopment of a TB green II-based duplex real-time The duplex qPCR could detect and differentiate PCV2 (melting peaks at 85.5 °C) and PCV3 (melting peaks at 82.5 °C),and showed high repeatability and reproducibility,with intra- and inter-assay coefficients of variation of less than 2.0%.Fifty-six tissue samples from 18 pig farms were used to evaluate the duplex qPCR method.
