From the Guideline on bioanalytical method validation (2009):

Within-run precision

For the validation of the within-run precision, there should be a minimum of five samples per concentration level at lloq, low, medium and high QC samples in a single run. The within-run CV should not exceed 15% for the QC samples, except for the LLOQ, which should not exceed 20%.

For the

validation of the between-run precision, LLOQ, low, medium and high QC samples from at least three runs analysed on at least two different days should be evaluated. The gap between run CV value for QC samples shall be less than 15% except for the LLOQ which should not exceed 20%.

Should between run precision and within run precision really take the definite article here? These phrases are parameter names, and the guideline does not refer to a particular “within-run precision” of a particular analytical method.

When going through an order a parameter name is used without a definite article. I always come across it.

How can

you measure the variation of Cricket Chirps and its temperature?

Ex. Temperature

=> Vapour => Temperature => Air Temperature => temperature => vapour => water => temperature => temperature => Vapour => water => temperature => vapour => temperature => vacuum => temperature => volume => vapour => air temperature => vapour => air temperature => water => temperature => humidity => vapour => air temperature => temperature => vapour => vacuum => temperature => velocity (==)

Why I’m sorry?
