HELP Seeking Analog Tool measures sample size/freq
March 24, 2006 at 7:33 pm #42853
When I was in college (Cal Polytechnic, SLO), I took a Quality Control class where we used an analog/manual device that could be called a ruler/gauge/calculator. This tool was used for gathering samples. It would calculate the desired sample size/frequency rate based on confidence levels and populations. I remember my teacher handing them out to our class.
Does anyone know the name of this tool?
Where I can acquire a few?
Please help me.0
