RE: Question regarding independent data

[Rip Stauffer <rstauffer@bluefirepartners.com>]

Carlos Mendez asked: "I wonder what happends when, in the case of batch by
batch production, a
supervisor makes adjustmes to a process for the next batch based on the
results of the previous batch. That is a sort of a funnel rule 4. ¿Would
this mean that in this case the data are not independent?"

It would certainly mean that the data were not independent, in this case
deliberately so. It would be a classic case of tampering, maybe rule 2, 3 or
4 (depending on the adjustment made).

Best regards to all,
