Power analyses and sample size calculations are important parts of many research projects. Often, before data are even collected, it is necessary to calculate and justify the required sample size for ...

When you measure RF emissions with a spectrum analyzer, you may need to measure the total power contained in a spread-spectrum signal. FCC part 15, subpart E (Ref. 1) requires these power measurements ...

Everyone has heard stories from parents and grandparents about how gas or milk costs so much more than it did when they were kids. Things were cheaper "back then," because, over the years, inflation ...

To calculate the statistical power for a given Type I error α, we first use equation (4) to find the critical value λ 1−α and then use equation (5) to calculate ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
