Q8+1_________ involves only two principles viz., the principle of replication and the principle of randomization of experimental designs. It is the simplest possible design and its procedure of analysis is also easier. The essential characteristic of the design is that subjects are randomly assigned to experimental treatments (or vice-versa)Choose one optionCompletely randomized designRandomized block designLatin square designFactorial designs

Real-world Application: These designs are common in real-world settings where random assignment is infeasible, such as in education, policy interventions, and organizational changes.
