Need to Estimate Uncertainty for some simple measurements
Need to Estimate Uncertainty for some simple measurements
(OP)
Does anyone know of a spreadsheet (Excel)?? or other source for estimating uncertainty in two (2) types of measurements:
Voltage readings with a Digital Fluke Meter
and
Force measurements with a Chatillan Digital Force Meter?
I am looking for a simple method to quantify the uncertainty for approximately 50 readings of ea. type to satisfy an ISO audit.

RE: Need to Estimate Uncertainty for some simple measurements
If you have analysis toolpack installed (assuming EXECEL) the choose "descriptive statistic". The function will give you mean, std. dev and some other info. Usually +/-3 sigma is considered the range that any measurement should be within (99.96 i think it would cover in the normal distribution).
If your uncertian on propability/statistics the help function isnt much help. You gotta know what your dooing up front.
