Data collection is a vital skill for any researcher or analyst, but it also comes with challenges and pitfalls. One of the most common and serious issues is measurement error, which occurs when ...

A much-cited study, according to which technical and scientific progress has produced fewer and fewer disruptive breakthroughs lately, reveals a "serious measurement error" at a crucial point.

The value of research in any topic area turns on its validity. Patient safety research has revealed—or, at least, given renewed urgency to—a raft of methodological issues. The meaning and thus the ...

DS2780 current measurement offset error is extremely dependent on board layout. The total loop area of the measurement circuit should be minimized to limit the ...

Random error (misclassification) in exposure measurements usually biases a relative risk, regression coefficient, or other effect measure towards the null value (no ...

Datasheets shows that INA238 has the same measurement accuracy as INA236. (5uV offset, 0.1% gain error,16 bits ADC…) However, customer’s testing data shows that the measurement errors of INA238 exceed ...

Does a resistance temperature detector (RTD) temperature measurement system have consistent errors? Can a high precision RTD temperature measurement system be designed without the need for calibration ...

The measurement process can be greatly simplified by using a servo loop to force a null at the amplifier input, thus allowing the amplifier under test to essentially measure its own errors. Figure 1 ...

The importance of calibration for all electronic test equipment. The main reason why such equipment must be regularly calibrated. The pros and cons of self-calibration or using outside services.

Diagnostic errors are associated with patient harm and suboptimal outcomes. Despite national scientific efforts to advance definition, measurement and interventions for diagnostic error, diagnosis in ...

Chodorow-Reich, Gabriel, John Coglianese and Loukas Karabarbounis. 2019. The Macro Effects of Unemployment Benefit Extensions: a Measurement Error Approach. The ...
