Ok, perhaps it will be easy to you but I need some basic help
I want to prove that in our analysis balances are the biggest source of variation. If it is of course. So really I want to find source of biggest variation.
The analysis is as follows - analyst weights the sample, does the solution by diluting the sample, and analyses it. There is a satndard of known potency weighted and analysed with the sample.
I can have 2 balances (I suspect both to work wrong), 2-3 analysts, 1 (or 2) equipment for measuring.
I would like to design a statistically sound study to find sources of variation. I think ANOVA is the way but ma not sure and also need help with design.
Do you need any more information? Does anything needs to be improved?
Please feel free to move the topic if this is not the place where I can get help. English is not my mother language so I have some difficulties in understanding this statistical concepts (I'm also not a statistician)
