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.

Designing a less perfect solution We used FlashyScience to teach students how to use micrometer screws and for the main investigation we used the University of Colorado Boulder’s PhET simulations and ...

This article discusses simple processes for addressing the random and systematic errors caused by the dead time in a gammaray spectrometer.

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 ...
