And I suggest you look back at your post that I was replying to.Uh, then you don't understand any of the protocols being proposed. I suggest you read back a few pages - or search on protocol on this thread.
There is nothing in here that indicates a second randomization for each test and placement of the container inside another container. When one uses "the canisters" in two successive paragraphs, I would assume he is referring to the same canisters, not another set of canisters in which the first set is placed after a randomization. In this description, you left out a critical step.At the start, 1 canister has the target. 9 are dummies. All are prepared and sealed in front of all participants and taped closed. The canisters are randomly numbered - but no one now nows which contains the target.
During the test the canisters are then randomly chosen to be placed on the test area (or at 10 different locations).
The randomising team records the number (1-10) of the canister and the order/location (a-j) it is taken to the test site.
