This article discusses important aspects of t-testing with the help of the example experiment presented in the previous article.
October 14, 2020 by Robert Keim
This article is the second in a two-part series that reviews the basics of electromagnetic compatibility tests. We'll now turn our attention to radiated EMC tests.
October 13, 2020 by Ignacio de Mendizábal
This article provides an example of how we can use t-testing to determine if an experiment has produced a statistically significant change in system performance.
October 12, 2020 by Robert Keim
This article is the first in a two-part series that reviews the basics of electromagnetic compatibility tests. First, we'll focus on a main category of EMC tests—conducted EMC—and the relevant test setup.
October 07, 2020 by Ignacio de Mendizábal
This article introduces a statistical distribution used in significance testing. We’ll discuss its importance and its relation with the normal distribution.
October 05, 2020 by Robert Keim
What exactly do scientists and researchers mean when they state that something is or is not statistically significant? How do we establish statistical significance, and how do we interpret it?
