Developing a method is an important part of planning an investigation. In an experiment, evaluate the validity of the steps leading up to the conclusion for it to be valid. Random and systematic ...
Systematic sampling means testing a hypothesis by taking several equally spaced items from a larger list, eg selecting the tenth, 20th and 30th visitor to a theme park. This can be particularly useful ...
Systematic errors are caused by defective parts like incorrectly adjusted optics or interfering influences such as a dirty light path, and can lead to measurement result deviation from the real value.
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 ...
