Thesis: In-stream sampling

(Read Sunday and Monday’s posts first)

In-stream sampling is one sampling method used to effective identify sampling units for the quality control sample.

Things that we must consider with this sampling design are

• which sampling units we wish to target (i.e. which sampling units we think the data collectors might make mistakes on)
• what prior information we have on the sampling units to use for targeting the selection process
• how to design the sample so that the data collect cannot predict when review will occur
• temporal aspects of the sampling rate (usually we wish to oversample at the beginning and ending of the sampling process when the data collectors are more prone to make errors)

I am researching what attributes are important in designing an in-stream sampling method to achieve the desired results.
