Hello,
I am interested in creating a database of certain properties of a material in order to have a reference for checking products that got rejected by the user.
the intent is to have a range of values for each property in order to place the rejected products properties in that range.
My question is how do i determine a sample size to create a reliable database?
the purpose is to check for material degradation on the rejected products.
the range will be made up from products with new material.
by comparing the rejected materials properties to the range I prepared, I can have an estimate of the degradation that took place.
Thank you!
