Completely randomized design is based on the principles of ______ and randomization only.
Replication.
The three basic principles of experimental design are randomization, replication, and local control.
A Completely Randomized Design (CRD) assumes homogeneous experimental units, so it does not use local control (blocking). It relies on only two principles: randomization (treatments assigned to units at random) and replication (each treatment applied to more than one unit, which gives the estimate of experimental error).
Hence the blank is Replication.
