Can you provide a link to that video? And also a link to a good example how they present the data and the different confounding factors? Do they pubish the data somewhere other than in the videos? Thanks 👍

Lets say you run a single test and collect 10 samples at steady-state for temperature and power. This data will have some degree of variability depending on many factors such as airflow at that exact moment, CPU utilization and also inherent noise in the measurement device itself. Additionally, if you repeat the same test multiple times on different days with different testers, you will not get the exact same results.

So if you then compare a system A to system B you might see that system B is 12% "better" (depending on your metric), then you must answer the question--> is this observed difference due to system B actually being better or can this difference be explained by the normal variability in your test setup. Most of the time there are so many external factors influencing your measurement that even if you see a difference in your data, this difference is not significant but due to chance. You should always present your data in a way that its clear to the reader how much variability was in your test setup.

All valid points. But regarding the measurements, neither LTT or GN testing methodology are realy scientific. Those are youtubers with limited understanding of experimental design and analysis. I have never seen them do simple significance tests or try to explain the variability in the data. But I havent watched all the videos so 乁⁠(⁠ ⁠•⁠_⁠•⁠ ⁠)⁠ㄏ
