In an experiment, evaluate the validity of the steps leading up to the conclusion for it to be valid. Random and systematic errors can contribute to the uncertainty of a measurement.

Physics requires students to analyse errors in data, discuss the causes of these errors and recommend ways experiments can be improved in the future. This requires lab work. When we moved online ...

Introduction Wearable sensor systems may be useful for measuring head-impact exposure. Here, we tested the validity of in-ear sensors developed to improve head coupling. Methods First, the sensor was ...

This article discusses simple processes for addressing the random and systematic errors caused by the dead time in a gramma-ray spectrometer. It also explains the applicability of the livetime clock ...

Global warming slowdown: No systematic errors in climate models, comprehensive statistical analysis reveals Date: February 2, 2015 Source: Max-Planck-Gesellschaft Summary: Skeptics who still doubt ...
