How to record and access the order of randomized blocks?
we have the following problem:
In our survey, participants complete 2 x 10 blocks. Each time, we randomly draw 10 blocks from a pool of 25 blocks.
We would like to have a history table that documents participant performance over time. Thus, in the second block of the first period, we'd like some kind of table that shows the specific variables from the first block. In the 9th block, we'd have a table with 8 columns for the first 8 rounds. Etc.
Is there a way to access/show an embedded data field conditional on when its block has been drawn by the randomizer?
