Balanced trial schedule
Export a reproducible, balanced C/D order across preparation days.
Calculator and method
Numeric inputs appear in a shared link. CSV data are kept out of the link.
Know what the result means.
Deterministic seeded pseudorandom schedule for planning. Keep the allocation key with a custodian for a blinded study. Random ordering does not establish independent days or remove carryover.
Version 1.0 · SI quantities are used internally, with displayed input units converted explicitly. Retain your assumptions with any exported result.
