| May 4, 2020 at 12:25 | comment | added | Ben | ok, thanks, I will look them up! Another a-bit-far-fetched question: I stumbled over the qualityTools for R and saw it can be used to check repeatability (also for experiment designs), explained here: rdrr.io/cran/qualityTools Are you familiar with that? I just want to know if it makes sense to use the cg-function where the target would be the mean of the data? It sounds legit for me.. | |
| May 4, 2020 at 12:15 | comment | added | Demetri Pananos | That isn't quite correct. A confidence interval tells you what values of the parameter (e.g. the mean) are consistent with the data you see. The standard deviation is a measure of spread, not a measure of quality. I would encourage you to perhaps revisit some of the material from an introductory resource on statistics. | |
| May 4, 2020 at 12:00 | comment | added | Ben | Thank you, I got that! So a confidence interval makes more sense when I want to know what the length of the ruler is, so I measure it 10 times and the CI would tell me how where 95% of the measurements will fall. Contrary to that, the standard deviation tells me how good I measure. Is that correct? | |
